Senior Senate Democrat Charles Schumer has called on Rep. Alan Grayson to drop out of his Senate primary campaign in Florida following allegations of domestic abuse.

Schumer, D-N.Y., who is in line to take over for retiring Harry Reid as Senate Democratic leader, told Politico that Grayson has “shown himself not to be worthy of being a U.S. senator.”

“I’ve never thought much about Grayson as a candidate,” Schumer told Politico, noting that’s why he and other colleagues are backing Democratic Rep. Patrick Murphy in the primary race.

He added, “He ought to do the right thing and drop out.”

Sources confirmed Schumer’s comments to Fox News. 

But Grayson's campaign is showing no signs of getting out of the race.

"Democratic voters in Florida, not out-of-touch party bosses in Washington, D.C., will be choosing our Senate nominee," campaign manager Michael Ceraso said. 

The pressure follows an earlier Politico report that Grayson’s ex-wife accused him of physically abusing her over two decades – though the Florida congressman vehemently disputed the claims.

Grayson’s wife, Lolita, repeatedly went to police with accusations of domestic abuse dating back to 1994, according to documents she provided to the website.

The police reports show she called police on Grayson at least two times in Virginia and two more times in Florida. In one instance, she told police Grayson had threatened to kill her, according to Politico.

The three-term House Democrat, however, denies he abused his former wife – and claims she battered him in 2014 before their 25-year marriage ended last year.

"Lolita is a disturbed woman. She has made one false allegation after another. Her own daughter refutes her," Grayson’s lawyer, Mark NeJame, told Politico.

The story set the stage for another confrontation earlier this week, when Grayson reportedly threatened to have a Politico reporter arrested at an event in Philadelphia, when the reporter tried asking questions.
