He said that despite Clinton's remarks, Sanders is "beloved" by the people in this country.

Moore's comments come amid several comments Clinton has made about Sanders, tearing open old scars from the 2016 election cycle.

In a podcast interview released on Friday, Clinton blamed “a lot of people highly identified with [Sanders’s] campaign” for urging Sanders supporters to vote for third party candidates in 2016. An effort she claims, helped Trump win the White House. She went on to say that Sanders's principal supporters were difficult to deal with and attacked Clinton and her supporters.

Previously, in an interview with the Hollywood Reporter, Clinton asserted that "nobody likes" Sanders and that he has not been able to get things done during his long career as a lawmaker.

Other Sanders surrogates besides Moore have criticized the former secretary's remarks. During a live campaign event in Iowa on Friday, Rep.

After the moderator tried to quell initial boos from the crowd, Tlaib jumped in saying, "I'll boo. Boo."

"You all know I can't be quiet," Tlaib added. "The haters will shut up on Monday when we win."

Following her comments, Tlaib apologized, vowing to "do better" and encouraged other Democrats to rally around whoever the Democratic nominee is at the end of the nominating process.

Despite her recent attacks on Sanders, Clinton has said that she will fully support whoever wins the Democratic nomination.

Sanders has also underscored that he too will support the winner.

“Certainly I hope that we’re going to win. But if we do not win, we will support the winner, and I know that every other candidate will do the same. We are united in understanding that we must defeat Donald Trump,” Sanders said.

The Iowa caucuses, the nation's first contest, are Monday.
