‘We risk allowing January 6 to become our future' -Rep. Raskin

Donald Trump's historic impeachment trial on a charge of inciting last month's deadly storming of the U.S. Capitol began on Tuesday (February 9), making the Republican the first former U.S. president to be tried in the Senate.

House of Representatives Democrats serving as prosecutors opened their case by showing video of Trump supporters violently overwhelming police at the Capitol in the Jan. 6 attack after he had encouraged people in a speech to "fight like hell" to overcome his Nov. 3 election defeat.

Raskin said Trump's lawyers are trying "to stop the Senate from hearing the facts."

"The January exception is an invitation to our founders' worst nightmare. ... We risk allowing Jan. 6 to become our future," he told the trial, in which senators serve as jurors.

Defense lawyers plan to argue on Tuesday that only a sitting president can face an impeachment trial.
