Vast right-wing conspiracy

"Vast right-wing conspiracy" is a phrase popularized by 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, U.S. President Bill Clinton, characterizing the continued allegations of scandal against her and her husband, including the Lewinsky scandal, as part of a conspiracy by Clinton's political enemies.

Into the 21st century, the term continued to be used, 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. Additionally, conservatives used or adopted the term to mock it.
