Minnesota Congresswoman Michele Bachmann joined a number of her House colleagues in demanding a thorough investigation of the IRS' targeting of the Tea Party and other conservative groups.
The IRS has acknowledged that some conservative groups were singled out for extra scrutiny when they applied for tax-exempt status in 2011 and 2012.
The Star Tribune reports Bachmann called the IRS controversy "far worse than Watergate."
"We also don't want to jump to conclusions, we want to go where the facts lead us," Bachmann, a Republican from Minnesota's sixth district who chairs the House Tea Party caucus, said at a press conference on Thursday.
But MPR notes that Bachmann had trouble sticking to that pledge during the press conference. She made a leap of logic that attempted to link the IRS scandal to the Affordable Care Act, or "Obamacare," which she has vehemently opposed, MPR reported.
MPR noted that she suggested - without elaborating - that the IRS may have access to private medical records and could use them to harass conservatives.
MinnPost sees a connection between Bachmann's mention of medical records and the bill she sponsored to repeal Obamacare. The House passed Bachmann's bill Thursday night on a nearly party-line vote. But it's unlikely to be taken up by the Democratic-controlled Senate.
The House Ways and Means Committee, which includes Minnesota Republican Erik Paulsen, will hold a hearing Friday morning on the IRS' targeting of conservative groups.
KSTP posted the video of the news conference Bachmann led calling for a complete investigation.
In a statement issued after the IRS acknowledged what it had done, Bachmann called the agency's actions a stunning abuse of power.
