A Democrat running in one of the reddest Senate races in the country says he will not vote for his own party's leader.

Adam Hamilton, who is challenging Republican Sen. Roger Marshall in Kansas, said he would not support Chuck Schumer as Democratic leader, whether his party wins the majority or not. "I support term limits," Hamilton told CBS News, according to Fox News. "I support age limits, and I just think there's a time where we need to have new and fresh leadership coming in, and I think this is one of those times."

He also said he meant "no disrespect" to Schumer. "We need new ideas, we need fresh leadership," he told CBS News, according to Fox News.

Hamilton, a Methodist megachurch pastor, calls himself an "independent-minded Democrat" and has kept away from party leaders in Washington, CNN reported. He had earlier told CNN he would not back Schumer. When a sitting Democratic senator offered to campaign for him, his team said no, CNN reported.

Schumer is not stepping aside. "I am running for re-election for leader. Period," he told Politico, Fox News reported. Schumer has led Senate Democrats since 2017 and says the party has "wind in our sails" heading into November.

Hamilton is not alone. Abdul El-Sayed in Michigan and Lt. Gov. Peggy Flanagan in Minnesota have also held back their support for Schumer, Fox News reported. Both have taken money from Senate Majority PAC, the super PAC closely tied to Schumer. Sen. Elissa Slotkin of Michigan has called for "significant new leadership," and some progressives have floated Sen. Chris Van Hollen of Maryland as a possible rival, Fox News reported. Van Hollen has not said whether he would run.

That same PAC is now putting $5 million into Kansas to help Hamilton, CNN reported.

What we know: Hamilton says he will not back Schumer, and Schumer says he is running for leader again.
What we don't: Whether more Democratic candidates will break with Schumer before Election Day.
