Senate Minority Whip Dick Durbin says President Trump has become a danger to the country and destroyed his credibility in front of the nation and the world.

Durbin, D-Ill., said on MSNBC Friday that Trump's tweets alluding to recordings of his conversations with ex-FBI Director James Comey is "another one of his fantasies that he's putting out before the public."

"President Trump is dangerous," Durbin said. "Dangerous because he may be obstructing justice in terms of the investigation that goes to the heart of our democracy … and secondly, his credibility has been destroyed."

He added, "You need to be credible not only in your own country but around the world."

Trump on Friday morning threatened to end White House press briefings because his spokespeople can't keep up with his fast-moving presidency and give accurate information. Shortly after that, he warned Comey against leaking the details of their conversations by alluding to possible recordings of their conversations.

Durbin said the entire Trump administration has credibility questions, including Attorney General Jeff Sessions.

Durbin said Sessions has an ethical cloud hanging over his head after Comey's dismissal.

"He recused himself from anything involving this Russian investigation and then is involved in dismissing the person who is leading that investigation," he said.
