This just in from the Associated Press (we added the boldface and link):
Freshman U.S. Rep. David Rivera, who is facing a state criminal investigation of his finances, paid himself nearly $60,000 in unexplained campaign reimbursements over the eight years he served in the state legislature, an Associated Press examination of his records shows.
Serving as his own campaign treasurer, the Miami Republican didn't report any details for more than a third of the roughly $160,000 in expenses for which he reimbursed himself, other than simply calling them campaign expenses, according to the records.
The AP review also shows his total reimbursements far exceeded those claimed by 12 other top Florida state legislators who served with him. Those lawmakers - both Democrats and Republicans - usually gave at least some explanation of how the money had been spent, as required by Florida law. Rivera denies wrongdoing.
