Rubio Calls Trump's Criticism of His Finances 'Ironic'

It's official: Presidential candidates Marco Rubio and Donald Trump are in a fight over finances.

"I find it ironic that the only person running for president that's ever declared a bankruptcy -- four times in the last 25 years -- is attacking anyone on finances," Rubio said on the campaign trail in New Hampshire on Thursday in response to questions Trump has been raising about the Florida senator's personal finances.

Trump has never filed for personal bankruptcy, but his company Trump Entertainment Resorts -- which he owned 28 percent of -- filed for bankruptcy four times, most recently in 2014.

Yesterday in New Hampshire Trump attacked Rubio on the issue.

"Marco Rubio has a disaster on his finances," Trump said. "He has a disaster on his credit cards...let's see what you find, let's see what kind of reporters you are. Won't be hard."

Before Rubio was a U.S. senator, he was Speaker of the House in Florida. During that time, he used a charge card issued by the state GOP party for personal expenses. Rubio argues that the card was mistakenly used, and he paid back the credit card company directly for personal expenses purchased on the card.

"Every month a bill came to my house and I would review it. If there was something personal I paid for it. If it was political the party paid for it. I didn't pay for it after the fact, I paid during the time," Rubio said in an interview with ABC News' Jonathan Karl yesterday.

Rubio also told ABC News that he would be releasing the charge card records.
