Even though Senator Harry Reid is a liberal, he is not a fan of fellow liberal Representative Alan Grayson of Florida. At a closed door meeting on Capitol Hill on Wednesday, things got ugly when Grayson confronted Reid and was shut down and told by the top Senate Democrat he hopes Grayson loses his primary race.

Grayson is running against Rep. Patrick Murphy in the primary to fill outgoing Senator Marco Rubio’s seat in Florida.

In February Reid endorsed Murphy even though he is more of a centrist and called upon Grayson to drop out of the race. He cited allegations that Grayson unethically promoted his Cayman Island hedge funds while serving in Congress.

Grayson was furious and decided to use Reid’s visit with the Congressional Progessive Caucus’s weekly lunch as a way to call him out. According to members at the meeting, Grayson stood up and repeatedly asked if Reid knew his name. He then demanded that Reid provide evidence to back up complaints about his business dealings, and Reid responded he thought the reports about his hedge funds were true and told him bluntly: “I want you to lose.”
