Betsey Ross Wright (born July 4, 1943) is an American lobbyist, activist, and political consultant who worked more than a decade for Bill Clinton in Arkansas.
 She served as chief of staff to Governor Clinton for seven years.
 As deputy chair of the 1992 Clinton presidential campaign, Wright established the rapid response system that was responsible for defending Clinton's record in Arkansas and promptly answering all personal attacks on the candidate.
 During the 1992 campaign, Wright coined the term "bimbo eruptions" to describe rumors alleging extramarital affairs by Clinton.
 In the 1990s, Wright was an executive for The Wexler Group, a lobbying firm in Washington, D.C. She currently resides in Rogers, Arkansas.
"Clinton crazies" is a term in American politics of the 1990s and later that refers to intense criticism of United States President Bill Clinton and his wife Hillary Clinton.
 The phrase is a succinct amalgamation of the claim by Clinton supporters who argue that Clinton opponents, throughout his presidency, "systematically ... sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office."
 Such intensity of feeling existed throughout the Clinton years, leading commentators to wonder what was at the root of it.
 The term was especially used in reference to people and media outlets that focused on all manner of Clinton scandals and controversies, some of which had substance behind them and some of which did not.
 In particular, there was a tendency towards the holding of conspiracy theories among these people and outlets.
Cheryl D. Mills (born 1965) is an American lawyer and corporate executive.
 She first came into public prominence while serving as deputy White House Counsel for President Bill Clinton, whom she defended during his 1999 impeachment trial.
 She has worked for New York University as Senior Vice President, served as Senior Adviser and Counsel for Hillary Clinton's 2008 presidential campaign, and is considered a member of Hillary Clinton's group of core advisers, self-designated as "Hillaryland".
 She served as Counselor and Chief of Staff to Hillary Clinton during her whole tenure as United States Secretary of State.
 After leaving the State Department in January, 2013, she founded BlackIvy Group, which builds businesses in Africa.
John David Podesta (born January 8, 1949) is a columnist and former chairman of the 2016 Hillary Clinton presidential campaign.
 He previously served as chief of staff to President Bill Clinton and Counselor to President Barack Obama.
"Vast right-wing conspiracy" is a conspiracy theory first described in a 1995 memo by political opposition researcher Chris Lehane and then referenced in 1998 by the then First Lady of the United States Hillary Clinton, in defense of her husband, President Bill Clinton, characterizing the continued allegations of scandal against her and her husband, including the Lewinsky scandal, as part of a long campaign by Clinton's political enemies.
 The term has been used since, including in a question posed to Bill Clinton in 2009 to describe verbal attacks on Barack Obama during his early presidency.
 Hillary Clinton mentioned it again during her 2016 presidential campaign.
Benjamin Swann (born July 17, 1978) is an American television news anchor and investigative journalist.
 He has worked in New Mexico, Texas, Ohio, Washington, D.C., and Georgia.
 While at Fox affiliate WXIX-TV in Cincinnati, Ohio, he began producing a fact-checking series entitled "Reality Check", which has garnered occasional media attention for questioning widely accepted narratives on high-profile controversies such as the Sandy Hook Elementary School shooting, the Pizzagate conspiracy theory, and an alleged link between vaccines and autism.
 After leaving WXIX-TV in 2013, Swann regularly appeared on RT America, part of the Russian state-owned TV network RT, while independently continuing to produce his show "Reality Check".
 In June 2015, Swann left RT America to join CBS affiliate WGCL-TV in Atlanta, Georgia as chief evening news anchor.
Pizzagate is a debunked conspiracy theory that emerged and went viral during the 2016 United States presidential election cycle.
 In the fall of 2016, the personal e-mail account of John Podesta, Hillary Clinton's campaign manager, was hacked in a spear-phishing attack and his e-mails were made public by WikiLeaks.
 Proponents of the Pizzagate theory falsely claimed that the e-mails contained coded messages referring to human trafficking and connecting a number of restaurants in the United States and members of the Democratic Party with an alleged child-sex ring.
 The theory has been extensively discredited by a wide array of organizations, including the District of Columbia Police Department.
The presidency of Bill Clinton began on January 20, 1993 at noon Eastern Standard Time, when Bill Clinton was inaugurated as President of the United States, and ended on January 20, 2001.
 Clinton, a Democrat, took office after defeating Republican incumbent President George H. W. Bush and Independent businessman Ross Perot in the 1992 presidential election.
 Four years later, he defeated Republican Bob Dole and Ross Perot (this time running on the Reform Party ticket) to win a second term of office.
 During both elections, Clinton ran as a New Democrat, and many of many of his administration's policy proposals reflected his centrist, Third Way thinking.
 The 42nd United States president, he was the first president elected after the end of the Cold War, the first Baby Boomer to become president, and also the first Democrat since Franklin D. Roosevelt to serve two full terms.
Ben Garrison is a cartoonist.
 He lives in Lakeside, Montana.
 His political views have been described as libertarian, and his cartoons often portray President Donald Trump in a favorable light.
 He has also drawn cartoons promoting the Pizzagate conspiracy theory and Seth Rich murder conspiracy theory.
 In a 2015 interview with Breitbart News, he said he did not support any presidential candidate in the 2016 election, but also said he admires Trump for "shaking up the neocon-controlled Republican Party."
 In May 2016, a cartoon of his comparing Michelle Obama and Melania Trump drew national attention.
The impeachment process of Bill Clinton was initiated by the House of Representatives on December 19, 1998, against Bill Clinton, the 42nd President of the United States, on two charges, one of perjury and one of obstruction of justice.
 These charges stemmed from a sexual harassment lawsuit filed against Clinton by Paula Jones.
 Clinton was subsequently acquitted of these charges by the Senate on February 12, 1999.
 Two other impeachment articles – a second perjury charge and a charge of abuse of power – failed in the House.
