Former Sen. Al Franken (D-MN) said Monday on CNN’s “News Night” that it was the “patriotic duty” of former officials who were in President Donald Trump’s administration to warn voters he is dangerous.

Anchor Abby Phillip said, “November looks likely to be a Biden Trump match-up. How do you think that goes if the election were held today?”

Franken said, “Polling today changes all the time, but I don’t know. It’s going to be a close election either way, that’s what I say. I would like to see people like James Mattis and John Kelly, can I read a couple of things? This is John Kelly on President Trump, ‘The depths of his dishonesty, Kelly was his chief of staff, ‘the depths of his dishonesty is just astounding to me. He is the most flawed person I’ve ever met in my life.’ Okay? This is James Mattis, ‘He is more dangerous than anyone I could ever imagine.’ I would like to see those former Trump administration officials start to say who this guy is.”
