“What bothers me about this president is not so much what he says, although he is so offensive," Sanders said on ABC's "This Week with George Stephanopoulos.”
"He talks about prison for his former opponent in a presidential election; this is not what presidents of the United States do," he added.

"I am more worried about what this president’s policies are in terms of telling the working people of this country during his campaign that he was going to stand with them," Sanders said.
"And yet he governs now as a representative of the billionaire class — tax breaks for the wealthy, cutting people off of health insurance, ignoring the needs of children, not dealing with the prescription drug crisis in this country that he said he was going to deal with," he added, describing Trump as "a pathological liar."
Sanders, however, avoided questioning the president's mental stability — a topic that has come up repeatedly this week after an explosive new book's release. The book, "Fire and Fury: Inside the Trump White House" by Michael Wolff, claims every White House aide is concerned about Trump's ability to lead the country.
