Context paragraphs:
Luis v. United States: Luis v. United States, 578 U.S. ___ (2016) was a case in which the Supreme Court of the United States held that the Sixth Amendment to the United States Constitution prohibits the pre-trial restraint of assets needed to retain a defendant's counsel of choice when those assets have not been used in conjunction with criminal activity.

Epperson v. Arkansas: Epperson v. Arkansas, 393 U.S. 97 (1968), was a United States Supreme Court case that invalidated an Arkansas statute that prohibited the teaching of human evolution in the public schools.  The Court held that the First Amendment to the United States Constitution prohibits a state from requiring, in the words of the majority opinion, "that teaching and learning must be tailored to the principles or prohibitions of any religious sect or dogma."  The Supreme Court declared the Arkansas statute unconstitutional because it violated the Establishment Clause of the First Amendment.  After this decision, some jurisdictions passed laws that required the teaching of creation science alongside evolution when evolution was taught.  These were also ruled unconstitutional by the Court in the 1987 case "Edwards v. Aguillard".

Excessive Bail Clause: The Excessive Bail Clause of the Eighth Amendment to the United States Constitution prohibits excessive bail set in pre-trial detention.

Massiah v. United States: Massiah v. United States, 377 U.S. 201 (1964), was a case in which the Supreme Court of the United States held that the Sixth Amendment to the United States Constitution prohibits the government from eliciting statements from the defendant about themselves after the point that the Sixth Amendment right to counsel attaches.

List of African-American United States Senators: The United States Senate has had ten African-American elected or appointed office holders.  The United States Senate is the upper house of the bicameral United States Congress, which is the legislative branch of the federal government of the United States.  The US Census Bureau defines African Americans as citizens or residents of the United States who have origins in any of the black populations of Africa.  The term is generally used for Americans with at least partial ancestry in any of the original peoples of sub-Saharan Africa.  During the founding of the federal government, African Americans were consigned to a status of second-class citizenship or enslaved.  No African American served in federal elective office before the ratification in 1870 of the Fifteenth Amendment to the United States Constitution.  The Fifteenth Amendment prohibits the federal and state governments from denying any citizen the right to vote because of that citizen's race, color, or previous condition of servitude.  Of the ten senators, six were popularly elected (including one that previously had been appointed by his state's governor), two were elected by the state legislature prior to the ratification of the Seventeenth Amendment to the United States Constitution in 1913 (which provides for the direct election of U.S. Senators by the people of each state), and two were appointed by a state Governor.  The 113th United States Congress (2013–15) marked the first time that two African Americans served concurrently in the Senate.

Equal Opportunity to Govern Amendment: The Equal Opportunity to Govern Amendment, also known as the Hatch Amendment, is a United States constitutional amendment proposed in July 2003 by Senator Orrin Hatch (R-Utah) to repeal the natural born citizen clause prohibiting citizens who were naturalized from holding the office of President or Vice President of the United States.  Hatch's amendment would allow anyone who has been a US citizen for twenty years to seek these offices.  In the wake of the California recall election, 2003, this proposal was widely seen as an attempt to make California Governor Arnold Schwarzenegger (born in Austria and naturalized in 1983) eligible for the presidency and is sometimes nicknamed "Arnold bill" or "Amend for Arnold".  However, there are other politicians who were not born as American citizens and therefore would benefit from such an amendment.  Notables include Michigan governor Jennifer Granholm (born in Canada, naturalized in 1980), former Florida Senator Mel Martinez (born in Cuba), former United States Secretary of State Madeleine Albright (born in Czechoslovakia), former Vermont governor Madeleine Kunin (born in Switzerland), and current Secretary of Transportation Elaine Chao (born in Taiwan).  The text of the amendment reads as follows:

Torcaso v. Watkins: Torcaso v. Watkins, 367 U.S. 488 (1961) was a United States Supreme Court case in which the court reaffirmed that the United States Constitution prohibits States and the Federal Government from requiring any kind of religious test for public office, in the specific case, as a notary public.

Bolling v. Sharpe: Bolling v. Sharpe, 347 U.S. 497 (1954), is a landmark United States Supreme Court case which deals with civil rights, specifically, segregation in the District of Columbia's public schools.  Originally argued on December 10–11, 1952, a year before "Brown v. Board of Education", 347 U.S. 483 (1954), "Bolling" was reargued on December 8 and 9, 1953, and was unanimously decided on May 17, 1954, the same day as "Brown."  The "Bolling" decision was supplemented in 1955 with the second "Brown" opinion, which ordered desegregation "with all deliberate speed."  "Bolling" did not address school desegregation in the context of the Fourteenth Amendment's Equal Protection Clause, which applies only to the states, but held that school segregation was unconstitutional under the Due Process Clause of the Fifth Amendment to the United States Constitution.  In "Bolling," the Court observed that the Fifth Amendment to the United States Constitution lacked an Equal Protection Clause, as in the Fourteenth Amendment to the United States Constitution.  The Court held, however, that the concepts of Equal Protection and Due Process are not mutually exclusive.

Saxbe fix: The Saxbe fix , or salary rollback, is a mechanism by which the President of the United States, in appointing a current or former member of the United States Congress whose elected term has not yet expired, can avoid the restriction of the United States Constitution's Ineligibility Clause.  That clause prohibits the President from appointing a current or former member of Congress to a civil office position that was created, or to a civil office position for which the pay or benefits (collectively, "emoluments") were increased, during the term for which that member was elected until the term has expired.  The rollback, first implemented by an Act of Congress in 1909, reverts the emoluments of the office to the amount they were when that member began his or her elected term.

Elaine Chao: Elaine Lan Chao (; born March 26, 1953) is an American politician who is the 18th and current United States Secretary of Transportation.  A member of the Republican Party, she was previously a cabinet member in the administration of George W. Bush.
