He’s not even sworn in yet, but Rep-elect David Rivera (R-FL) is already disclosing questionable campaign loans.

Incoming Congressman David Rivera has admitted receiving $137,000 in undisclosed loans from a company co-owned by his mother — a company now under criminal investigation over secret payments from the Flagler Dog Track during its campaign to bring slot machines to Miami-Dade pari-mutuels.

Rivera told the Associated Press in an interview Monday that he repaid the $137,000 to his mother’s company, Millennium Marketing, sometime last year. Rivera also said he reported the loan in a new financial disclosure form he filed Monday with the U.S. House of Representatives, two days before he is expected to take the oath of office and begin his first term in Congress.

Rivera, a Republican from Miami, had never previously disclosed any loans from Millennium in financial statements filed as a congressional candidate, or during his prior tenure in the Florida legislature.

I’m sure it’s just an oversight on his part; those forms are so complicated, and who remembers every little thing?
