California billionaire release $10m for campaign to impeach Trump

California billionaire and Democratic mega-donor, Tom Steyer has announced his intention to spend at least $10 million on a national television advertising campaign calling for the impeachment of US president, Donald Trump.

The campaign is a bid by Steyer - to "demand that elected officials take a stand" on an issue Democratic leaders have so far largely avoided.

In the ad, Steyer argues Trump should be ousted from office because he has edged the country toward nuclear war, obstructed justice at the FBI and threatened to shut down news organizations he does not like. He urges viewers to call their members of Congress and tell them to bring articles of impeachment.

People in Congress and his own administration know this president is a clear and present danger who is mentally unstable and armed with nuclear weapons," Steyer says in the ad. And they do nothing.

Steyer plans to spend eight figures to air the television ads nationally, but would not give an exact amount.
