Donald Trump has now become the first US president in history to be impeached twice, after being charged with “incitement of insurrection” over last week’s deadly storming of Congress.

Mr Trump was accused by The House of Representatives of encouraging violence with his false claims of election fraud.

He now faces trial in the upper chamber, the Senate, but not before he leaves office next Wednesday.

Senators can vote to bar him from ever holding public office again.

In a video released on Wednesday, Mr Trump called on his followers to remain peaceful, without mentioning his impeachment.

“Violence and vandalism have no place in our country… No true supporter of mine would ever endorse political violence,” he said, striking a sombre and conciliatory tone.

Meanwhile the FBI has warned of possible armed protests planned for Washington DC and all 50 US state capitals in the days before Joe Biden is inaugurated as the new president of the United States
