590-1096: A president of the United States in Congress Assembled to preside over its deliberation as a neutral discussion moderator . Unrelated to and quite dissimilar from the later office of president of the United States, it was a largely ceremonial position without much influence. In 1783, the Treaty of Paris secured independence for each of the former colonies. With peace at hand, the states each turned toward their own internal affairs. By 1786, Americans found their continental borders besieged and weak and their respective economies in crises as neighboring states agitated trade rivalries with one another. They witnessed their hard currency pouring into foreign markets to pay for imports, their Mediterranean commerce preyed upon by North African pirates , and their foreign-financed Revolutionary War debts unpaid and accruing interest. Civil and political unrest loomed. Events such as
708-511: A "disruptive" erosion of his ability to govern. Ford failed to win election to a full term and his successor, Jimmy Carter , failed to win re-election. Ronald Reagan , who had been an actor before beginning his political career, used his talent as a communicator to help reshape the American agenda away from New Deal policies toward more conservative ideology. With the Cold War ending and
826-582: A NIST team as part of a DARPA competition. In September 2013, both The Guardian and The New York Times reported that NIST allowed the National Security Agency (NSA) to insert a cryptographically secure pseudorandom number generator called Dual EC DRBG into NIST standard SP 800-90 that had a kleptographic backdoor that the NSA can use to covertly predict the future outputs of this pseudorandom number generator thereby allowing

Bill Wilson , board member of Americans for Limited Government , opined that the expanded presidency was "the greatest threat ever to individual freedom and democratic rule". Article I, Section 1 of the Constitution vests all lawmaking power in Congress's hands, and Article 1, Section 6, Clause 2 prevents
1652-466: A month after taking office. Presidents often grant pardons shortly before leaving office, like when Bill Clinton pardoned Patty Hearst on his last day in office; this is often controversial . Two doctrines concerning executive power have developed that enable the president to exercise executive power with a degree of autonomy. The first is executive privilege , which allows the president to withhold from disclosure any communications made directly to
1770-970: A number of issues, including representation and voting, and the exact powers to be given the central government. Congress finished work on the Articles of Confederation to establish a perpetual union between the states in November 1777 and sent it to the states for ratification . Under the Articles, which took effect on March 1, 1781, the Congress of the Confederation was a central political authority without any legislative power. It could make its own resolutions, determinations, and regulations, but not any laws, and could not impose any taxes or enforce local commercial regulations upon its citizens. This institutional design reflected how Americans believed
1888-431: A presidential veto, it requires a two-thirds vote of both houses, which is usually very difficult to achieve except for widely supported bipartisan legislation. The framers of the Constitution feared that Congress would seek to increase its power and enable a "tyranny of the majority", so giving the indirectly elected president a veto was viewed as an important check on the legislative power. While George Washington believed
2006-539: A program to provide metrology services for United States scientific and commercial users. A laboratory site was constructed in Washington, DC , and instruments were acquired from the national physical laboratories of Europe.

The report noted that impeachment by Congress
2242-476: A similar broadcast format. Like WWV, WWVH's main function is the dissemination of the official U.S. Government time and frequency standard. Due to ionospheric conditions, at certain times and locations some listeners may receive both WWV and WWVH on the same frequency at the same time. The information modulated on the carrier is modified to reduce confusion if both are received simultaneously. In particular, voice announcements on one correspond to silent periods on

Abraham Lincoln was deeply involved in overall strategy and in day-to-day operations during the American Civil War , 1861–1865; historians have given Lincoln high praise for his strategic sense and his ability to select and encourage commanders such as Ulysses S. Grant . The present-day operational command of
2478-550: A state visit by a foreign head of state, the president typically hosts a State Arrival Ceremony held on the South Lawn , a custom begun by John F. Kennedy in 1961. This is followed by a state dinner given by the president which is held in the State Dining Room later in the evening. As a national leader, the president also fulfills many less formal ceremonial duties. For example, William Howard Taft started

Within the Executive Office, the president's innermost layer of aides, and their assistants, are located in the White House Office . The president also possesses the power to manage operations of
9204-474: The head of the executive branch, presidents control a vast array of agencies that can issue regulations with little oversight from Congress. In the 20th century, critics charged that too many legislative and budgetary powers that should have belonged to Congress had slid into the hands of presidents. One critic charged that presidents could appoint a "virtual army of 'czars'—each wholly unaccountable to Congress yet tasked with spearheading major policy efforts for
9322-422: The legislature to a single term only, sharing power with an executive council, and countered by a strong legislature. New York offered the greatest exception, having a strong, unitary governor with veto and appointment power elected to a three-year term, and eligible for reelection to an indefinite number of terms thereafter. It was through the closed-door negotiations at Philadelphia that the presidency framed in

The Bureau took custody of the copies of the kilogram and meter bars that were the standards for US measures, and set up
9676-429: The network perimeter. ZTA utilizes zero trust principles which include "never trust, always verify", "assume breach" and "least privileged access" to safeguard users, assets, and resources. Since ZTA holds no implicit trust to users within the network perimeter, authentication and authorization are performed at every stage of a digital transaction. This reduces the risk of unauthorized access to resources. NIST released
9794-567: The office as a position of global leadership. His successors, Harry Truman and Dwight D. Eisenhower , each served two terms as the Cold War led the presidency to be viewed as the " leader of the free world ", while John F. Kennedy was a youthful and popular leader who benefited from the rise of television in the 1960s. After Lyndon B. Johnson lost popular support due to the Vietnam War and Richard Nixon 's presidency collapsed in
9912-423: The original.] In the modern era, pursuant to the War Powers Resolution , Congress must authorize any troop deployments longer than 60 days, although that process relies on triggering mechanisms that have never been employed, rendering it ineffectual. Additionally, Congress provides a check to presidential military power through its control over military spending and regulation. Presidents have historically initiated
10030-685: The other. WWVH uses a female voice ( Jane Barbe ) to distinguish itself from WWV, which uses a male voice. WWVH time signals can also be accessed by telephone at +1 (808) 335-4363. WWVH broadcasts its signal on four transmitters, one for each frequency. The 2.5 MHz transmitter puts out 5 kW, while the other transmitters provide 10 kW. The 2.5 antennas are one quarter- wavelength tall, and radiate in an omnidirectional pattern. The 10.0 and 15.0 MHz antennas are omnidirectional half-wave antennas. The 5 MHz antenna consists of two elements one half-wavelength tall and horizontally separated by one quarter-wavelength. This directional antenna produces
10148-524: The president (and all other executive branch officers) from simultaneously being a member of Congress. Nevertheless, the modern presidency exerts significant power over legislation, both due to constitutional provisions and historical developments over time. The president's most significant legislative power derives from the Presentment Clause , which gives the president the power to veto any bill passed by Congress . While Congress can override
10266-406: The president believes are needed. Additionally, the president can attempt to shape legislation during the legislative process by exerting influence on individual members of Congress. Presidents possess this power because the Constitution is silent about who can write legislation, but the power is limited because only members of Congress can introduce legislation. The president or other officials of
10384-461: The president in the performance of executive duties. George Washington first claimed the privilege when Congress requested to see Chief Justice John Jay 's notes from an unpopular treaty negotiation with Great Britain . While not enshrined in the Constitution or any other law, Washington's action created the precedent for the privilege. When Nixon tried to use executive privilege as a reason for not turning over subpoenaed evidence to Congress during
10502-556: The president is authorized to adjourn Congress if the House and Senate cannot agree on the time of adjournment; no president has ever had to exercise this power. Suffice it to say that the President is made the sole repository of the executive powers of the United States, and the powers entrusted to him as well as the duties imposed upon him are awesome indeed.

10856-555: The president the power to sign or veto federal legislation. Since modern presidents are typically viewed as leaders of their political parties, major policymaking is significantly shaped by the outcome of presidential elections, with presidents taking an active role in promoting their policy priorities to members of Congress who are often electorally dependent on the president. In recent decades, presidents have also made increasing use of executive orders , agency regulations, and judicial appointments to shape domestic policy. The president
10974-505: The president to "receive Ambassadors." This clause, known as the Reception Clause, has been interpreted to imply that the president possesses broad power over matters of foreign policy, and to provide support for the president's exclusive authority to grant recognition to a foreign government. The Constitution also empowers the president to appoint United States ambassadors, and to propose and chiefly negotiate agreements between
11092-516: The president to recommend such measures to Congress which the president deems "necessary and expedient". This is done through the constitutionally-based State of the Union address, which usually outlines the president's legislative proposals for the coming year, and through other formal and informal communications with Congress.

In addition, John Werner Cahn was awarded the 2011 Kyoto Prize for Materials Science, and
11682-424: The privilege also could not be used in civil suits. These cases established the legal precedent that executive privilege is valid, although the exact extent of the privilege has yet to be clearly defined. Additionally, federal courts have allowed this privilege to radiate outward and protect other executive branch employees but have weakened that protection for those executive branch communications that do not involve
11800-515: The privilege in more cases and at earlier stages of the litigation, thus in some instances causing dismissal of the suits before reaching the merits of the claims, as in the Ninth Circuit 's ruling in Mohamed v.

NIST also
12036-500: The process for going to war, but critics have charged that there have been several conflicts in which presidents did not get official declarations, including Theodore Roosevelt 's military move into Panama in 1903, the Korean War , the Vietnam War , and the invasions of Grenada in 1983 and Panama in 1989. The amount of military detail handled personally by the president in wartime has varied greatly. George Washington,
12154-481: The public convenience. In 1821, President John Quincy Adams declared, "Weights and measures may be ranked among the necessities of life to every individual of human society.". Nevertheless, it was not until 1838 that the United States government adopted a uniform set of standards. From 1830 until 1901, the role of overseeing weights and measures was carried out by the Office of Standard Weights and Measures, which
12272-493: The size and scope of the federal government, including more executive agencies. The traditionally small presidential staff was greatly expanded, with the Executive Office of the President being created in 1939, none of whom require Senate confirmation.

12390-431: The standard by NSA). NIST responded to the allegations, stating that "NIST works to publish the strongest cryptographic standards possible" and that it uses "a transparent, public process to rigorously vet our recommended standards". The agency stated that "there has been some confusion about the standards development process and the role of different organizations in it...The National Security Agency (NSA) participates in
12508-470: The surreptitious decryption of data. Both papers report that the NSA worked covertly to get its own version of SP 800-90 approved for worldwide use in 2006. The whistle-blowing document states that "eventually, NSA became the sole editor". The reports confirm suspicions and technical grounds publicly raised by cryptographers in 2007 that the EC-DRBG could contain a kleptographic backdoor (perhaps placed in
12626-622: The tradition of throwing out the ceremonial first pitch in 1910 at Griffith Stadium , Washington, D.C., on the Washington Senators's Opening Day .

Every president since Theodore Roosevelt has served as honorary president of
12744-407: The veto by its ordinary means, a two-thirds vote in both houses. In Clinton v. City of New York , 524 U.S. 417 (1998), the U.S. Supreme Court ruled such a legislative alteration of the veto power to be unconstitutional. For most of American history, candidates for president have sought election on the basis of a promised legislative agenda. Article II, Section 3, Clause 2 requires
12862-528: The veto should only be used in cases where a bill was unconstitutional, it is now routinely used in cases where presidents have policy disagreements with a bill. The veto – or threat of a veto – has thus evolved to make the modern presidency a central part of the American legislative process.

In addition, NIST partners with 1,400 manufacturing specialists and staff at nearly 350 affiliated centers around
13098-569: Was a significant milestone, as Jackson was not part of the Virginia and Massachusetts elite that had held the presidency for its first 40 years. Jacksonian democracy sought to strengthen the presidency at the expense of Congress, while broadening public participation as the nation rapidly expanded westward. However, his successor, Martin Van Buren , became unpopular after the Panic of 1837 , and

NIST Laboratories include: Extramural programs include: NIST's Boulder laboratories are best known for NIST‑F1 , which houses an atomic clock . NIST‑F1 serves as the source of the nation's official time. From its measurement of the natural resonance frequency of cesium —which defines the second —NIST broadcasts time signals via longwave radio station WWVB near Fort Collins , Colorado, and shortwave radio stations WWV and WWVH , located near Fort Collins and Kekaha, Hawaii , respectively. NIST also operates
13806-429: Was the first branch of government described in the Constitution , to be the dominant branch of government; however, they did not expect a strong executive department. However, presidential power has shifted over time, which has resulted in claims that the modern presidency has become too powerful, unchecked, unbalanced, and "monarchist" in nature. In 2008 professor Dana D. Nelson expressed belief that presidents over
13924-752: Was the most recent to do so in July 1948, known as the Turnip Day Session . In addition, prior to ratification of the Twentieth Amendment in 1933, which brought forward the date on which Congress convenes from December to January, newly inaugurated presidents would routinely call the Senate to meet to confirm nominations or ratify treaties. In practice, the power has fallen into disuse in the modern era as Congress now formally remains in session year-round, convening pro forma sessions every three days even when ostensibly in recess.
