John Oliver: Why Donald Trump's 'rigged' election claim is 'legitimately dangerous'

John Oliver had a lot to recap on Sunday's "Last Week Tonight" following Republican presidential candidate Donald Trump's interesting week. 

Along with a number of women accusing Trump of sexual misconduct, after the release of "Access Hollywood" footage of Trump bragging about sexually assaulting women, the GOP candidate doubled down on suggestions that the election is "rigged."

"Telling your supporters the election is being rigged is legitimately dangerous because faith in fair elections and in peaceful transfer of power are essential foundations for a democracy," Oliver said. 

Though a major candidate calling the presidential election rigged is unheard of in modern American history, it's only the latest first in a Trump candidacy that now has the shackles "off," as Trump tweeted:

"Just to recap this week," Oliver said, "Trump has declared war on his political opponents, the media, his own party, his own campaign, and the concept of democracy itself."
