PHILADELPHIA (CBSMiami/AP) — Senate Minority Leader Harry Reid says fellow Democrat Alan Grayson should drop his bid for Senate in Florida following reports that he physically abused his ex-wife.

Reid says Grayson is an “absolute fraud” and says: “Now having whacked his ex-wife around a few times … I don’t know who supports him other than himself.”

Reid has tangled in the past with Congressman Grayson, an unpredictable firebrand who is defying Democratic leaders’ wishes by challenging their favored candidate, Rep. Patrick Murphy, in the Aug. 30 Florida primary.

The new reports of abuse, first published by Politico this week, have increased pressure on Grayson, who has lost endorsements from two progressive groups.

Grayson’s spokeswoman did not immediately respond to a request for comment.

Incumbent GOP Sen. Marco Rubio is running for re-election.
