"I'm thoroughly convinced that I'll be cleared," Bachmann insisted.
Bachmann was at the Minnesota Capitol on Tuesday to join Republican State Sen. Sean Nienow, of Cambridge, to call for an audit of Medicaid both in the state and nationwide. A report last month showed Minnesota overpaid HMOs like Health Partners and Medica by at least $207 million.
Nienow has introduced a bill that would allow the state to recoup its overpayment.
Bachmann attended the conference in support of the audit and Nienow's bill; however, the spotlight quickly shifted to her presidential campaign's ethics investigation afterward.
At the center of the probe are allegations of improper fund transfers involving the campaign's national political director, Guy Short. Bachmann's Iowa campaign chairman, state Sen. Kent Sorenson, is also purportedly related to the improper funding.
"Well, [the claims are] absolutely not true," Bachmann said.
The OCE began investigating Bachmann's campaign finances after a complaint was filed with the Federal Election Commission over payments made to a public official in Iowa.
"Clearly, it looks like it's politically motivated and it's not true," Bachmann said. "I'm working very closely with the people involved to make sure we answer all the questions and get to the bottom of it."
When questions shifted from the Medicaid audit to Bachmann's campaign finance investigation, the congresswoman's aides quickly ushered her out of the room, blocking reporters and news photographers.
