Documentary filmmaker Michael Moore told MSNBC’s Ari Melber Monday that he was disappointed by former South Bend, Indiana Mayor Pete Buttigieg and Minnesota Senator Amy Klobuchar dropping their presidential bids the day before Super Tuesday.

Moore, a vocal supporter of Vermont Senator Bernie Sanders, said the Democrats are more worried about dampening Sanders’ popularity than they are defeating incumbent President Donald Trump.

“They did everything they could up to this point,” Moore said. “They couldn’t stop the momentum. It’s so sad that Mayor Pete and Amy couldn’t even, they couldn’t even go 24 more hours.”

“It wasn’t going to cost them any more money, it wasn’t going to cost them any more work,” Moore added. “They’ve put a year of their lives into this.”

Moore also questioned the timing of the candidates suspending their campaigns in order to endorse Biden.

“Tell me one time when you’ve seen major candidates, especially Mayor Pete who won and tied an election, a primary, when we’ve seen them drop out the night before the big enchilada,” Moore said.

“You know when they drop out?” Moore asked. “Say, the day after the Super Tuesday primary. Who drops out the night before?”

Newsweek reached out to Moore for comment but did not receive a response in time for publication.

Biden’s campaign has undergone a resurgence since his victory Saturday in the South Carolina primaries. His long affiliation with the African-American community in the state, as well as serving as vice president under President Barack Obama, helped him capture 39 delegates with 48.4 percent of the vote.

Sanders came in a distant second with almost 20 percent of the vote, picking up 15 delegates.

Monday in Utah, Sanders told reporters that Biden’s high-profile endorsements were not surprising to him.

“The corporate establishment is coming together,” Sanders said. “The political establishment is coming together and they will do everything. They are really getting nervous that working people are standing up.”

Biden has tenaciously gone after Sanders on his past voting record on gun control including his vote against the Brady Bill, which supports background checks for firearms purchasers and a five-day waiting period between the purchase and the delivery of a handgun. Sanders also supported legislation that prohibited suing gun manufacturers.

“Bernie voted five times against the Brady Bill and wanted a waiting period of 12 hours,” Biden said during the South Carolina Democratic debate in February.

“The biggest mistake that Bernie made, that Senator Sanders made, he voted to give the gun manufacturers, the only major industry in America, a loophole that does not allow them to be sued for the carnage they are creating,” Biden added. “First thing I’ll do as president is work to get rid of that.”

Sanders defended his voting record saying, “30 years ago, I likely lost a race for the one seat in Congress in Vermont because 30 years ago I supported a ban on assault weapons. Right now, my view is we need to expand background checks, end the gun show loophole and do what the American people want, not what the NRA wants.”
