(Associated Press) – Former California Governor Arnold Schwarzenegger described President Donald Trump as a failed leader “who will go down in history as the worst president ever.”

In a video posted on social media on Sunday, the Republican expressed his condolences that the Trump presidency was about to expire and “will soon become as irrelevant as an old tweet.”

He called for national unity and pledged to support President-elect Joe Biden in the wake of the mob and the breach of security at the US Capitol building – which forced the suspension of the electoral count when the Senate and House of Representatives were forced to make a cover decision due to the pro-Trump mob.

Five people, including a police officer, were killed in the Capitol. Dozens of rioters have been arrested and many are being sought after the brazen attack on the country’s institutions of power.

He said, “And for those who think they can repeal the United States Constitution, know this: You will never win.”

During the video, which lasted more than seven and a half minutes, Schwarzenegger likened American democracy to the sword he waved in his films, which he said only gets stronger when tempered.

Schwarzenegger, best known for his role in the movie Terminator, was elected governor in 2003 during a special recall election. He was subsequently elected to full term as governor of the nation’s most populous state.

“I think, as we were shaken by the events of the last days, we will come out stronger because we now understand what we can lose,” he said, adding that those behind the riots on Wednesday – and those who sparked them – will be held accountable.
