The tension between MSNBC and Sen. Bernie Sanders appears to be thawing.

MSNBC host Chris Matthews apologized to the 2020 Democratic candidate on Monday night for comparing Sanders’s victory in the Nevada caucuses to the Nazi invasion of France.

"I was wrong to refer to an event from the last days, or, actually, the first days, of World War II," he said. "Sen. Sanders, I’m sorry for comparing anything from that tragic era, in which so many suffered, especially the Jewish people, to an electoral result in which you were the well-deserved winner."

Sanders campaign manager Faiz Shakir told the Washington Examiner that the campaign does “appreciate some of the steps MSNBC has taken, and we hope to get fairer coverage going forward.”

Tensions between the two entities escalated last week when Sanders reportedly berated MSNBC President Phil Griffin before Thursday’s presidential debate.

“Phil, your network has not been playing a fair role in this campaign. I am upset. Is anything going to change? ... I hope you will do better,” Sanders said.

Network sources told Vanity Fair that Griffin has been taking the complaints seriously. After Matthews made the Nazi comparison, he addressed the matter with the host. MSNBC also aired two Sanders campaign rallies live on Saturday, and Shakir and former campaign manager Jeff Weaver both received airtime on Monday.

“The Sanders team is in contact with our senior management,” one source said, “and they are heard. Phil is doing his best to give Bernie his due.”

"The race has changed over the last couple of weeks, and we are going to reflect that and make adjustments. One easy way to do that is to seek out more smart, pro-Sanders voices from people who can make our coverage more insightful," a network executive told the outlet while adding, "Their campaign, like any other, is due fair coverage, not fawning coverage."
