Allegations of Central Florida Congressman Alan Grayson, who represents Florida's 9th Congressional District, which includes Osceola County, as well as parts of Orange and Polk counties, using his office to unethically promote a hedge fund continue to concern some political leaders.

And now U.S. Representative Patrick Murphy, who’s running against Grayson for U.S. Senate, is calling on Grayson to come clean.

This recent battle between democrats comes after the New York Times reported that Grayson traveled internationally using taxpayer’s money to promote his hedge fund.

Congressman Murphy, who represents the Port St. Lucie area, is competing against Grayson for the Democratic nomination to replace Senator Marco Rubio. He’s now asking Grayson to shut down the hedge funds he manages.

“It’s clear that he used his official position for personal gain and that is not only unacceptable but unethical. Alan Grayson has broken the trust of the voters who have put him in office,” said Murphy.

On Friday, the Senate’s top democrat, Senate Minority Leader Harry Reid, called on Grayson to drop out of the race. Grayson is refusing to give up his bid and says that Reid's actions are politically motivated.

Political experts weighed in on the fast-moving developments.

“I think Grayson needs to come back swinging… He needs to say Harry Reid who called for my resignation, called for me to get out of this race… He needs to fess up that he is supporting Patrick Murphy in this-- his opponent. This is a big ole nothing burger,” said Republican political analyst Michelle Ertel.

“So I think what he needs to do is bring out all the facts to bear and if it comes out that he has no wrongdoing then I think it can actually help his campaign,” said Democratic political analyst Jeremiah Jaspon.

Grayson’s campaign released the following statement Sunday:

Congressman Grayson did nothing unethical, illegal or even fattening, so Wall Street's errand boy should stop this desperate, issue-phobic smear campaign, and be more respectful to voters.

Congressional rules ban house members from holding outside jobs that bring in more than $27,000 a year. Grayson’s campaign says he’s never brought in anywhere near that amount while working in Washington, D.C.
