Sanders Repeatedly Refuses to Endorse Clinton

Senator Bernie Sanders (I., VT.) repeatedly dodged MSNBC's Chris Hayes questions on whether he would endorse Hillary Clinton Thursday evening.

NPR reported Vice President Joe Biden had said in an interview with Rachel Martin, that after talking with Sanders – the senator was going to endorse Clinton. Biden added that "this is going to work out."

Sanders told Hayes that he had talked to Biden three weeks ago and was more focused on the Democratic National Convention's platform.

"We are trying to work with Secretary Clinton's campaign on areas that we can agree on where the people can support it," Sanders said.

Hayes said that there was a difference between voting and endorsing, he then asked Sanders if he could see himself out on the campaign trail for Clinton.

"Well Chris, let me back it up by saying that I'm going to do everything I can to defeat Donald Trump," Sanders said. "I think, for a variety of reasons, number one, he's a pathological liar. That's not a good quality to have in a president. Number two, he wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of one percent by repealing the estate tax. He thinks that climate change is a hoax and maybe most importantly we cannot have a president who goes around insulting Mexicans and latinos and Muslims and women and African Americans. I mean that's just outrageous. I'm going to do everything that I can to see that Donald Trump is defeated."

Hayes pressed Sanders on his statement of  "doing everything that I can" by asking if that meant going to rallies and endorsing the Democratic party's candidate.

Sanders deferred and said that his focus was making the Democratic platform more progressive than it has been in the past and that he was going to continue to work and fight for that.
