“Fair or unfair, she is to many of the Bernie [Sanders] supporters somebody who really gets them riled up,” McCaskill added.

The Hill reported Tuesday that Democrats are debating whether the Florida Democrat should vacate her role as DNC chairwoman.

“We can argue about why that is or if it’s fair that that’s the case, but this will ultimately be up to Debbie. I think we all need to figure out how to get along. We’ve got to land this plane,” McCaskill said.

Critics say Wasserman Schultz’s handling of the presidential primary has alienated Sanders and his supporters, risking unity ahead of the general election this fall.

A top aide to Sanders on Wednesday said he would support Wasserman Schultz stepping down.

“Someone else could play a more positive role,” campaign manager Jeff Weaver said on CNN.

But McCaskill on Thursday said there is no Democratic support for Wasserman Schultz’s ouster.

“No one is calling on Debbie Wasserman Schultz to step down,” she said. "I don’t think anybody is trying to move Debbie out.

McCaskill added that a united front is essential for Democrats if they want to keep Trump from the presidency.

“I’m confident it will get worked out because we can’t have a reality TV star that has no concept of public policy set foot in the Oval Office,” she said of the GOP’s presumptive presidential nominee. "He cannot have the nuclear codes.”

Clinton remains the Democratic presidential front-runner nationwide, boasting 1,768 delegates to Sanders’s 1,497. At least 2,382 are needed for avoiding a contested convention in July.
