In August 1974, the 37th President of the United States - Richard Nixon - resigned after being told by members of his own Republican party that they could no longer support him. Evidence brought during the process to impeach and remove him had implicated the White House in an attempt to sabotage President Nixon's Democratic rivals. The allegations against President Nixon were similar in nature to those levelled at the 45th President Donald Trump. But this week, Mr Trump was acquitted of the two charges against him following his impeachment trial, after Republicans in the Senate voted not to hear new evidence in the case.
