Richard Nixon leaving White House grounds by helicopter after resignation.

In October 1973, President Richard Nixon committed the “Saturday Night Massacre,” in which he fired the Watergate Special Prosecutor who had been appointed at the behest of Congress, which caused the U.S. Attorney General and Deputy Attorney General to resign. Nixon also abolished the office of the special prosecutor. This Constitutional crisis, which occurred nearly five years into Nixon’s presidency, ultimately led to Nixon’s impeachment and his resignation.

Last night, after just 10 days in the White House, Donald Trump had a Saturday Night Massacre of his own. Trump fired Acting Attorney General Sally Yates after Yates wrote a letter to top Justice Department lawyers, directing them not to defend Trump’s Muslim immigration ban in federal court. Trump also fired Acting Director of Immigration and Customs Enforcement (ICE) Daniel Ragsdale, for reasons thus far unspecified. Several days earlier, Trump fired top career officers in the State Department.
