Utah Rep. Jason Chaffetz, chairman of the House Committee on Oversight and Government Affairs, is tired of fighting to get information from the IRS on its targeting of conservative and Tea Party groups during the 2012 election cycle.

On Monday, Chaffetz sent a letter to President Obama calling for the firing of IRS chief John Koskinen, who he says has obstructed the committee’s investigation for years.

Fox News reports:

“Mr. Koskinen should no longer be the IRS commissioner,” Chaffetz said in prepared remarks for a Capitol Hill press conference announcing his request. “At best, Commissioner Koskinen was derelict in his duties to preserve agency records. At worst, he and the IRS engaged in an orchestrated plan to hide information from Congress.”

It’s too bad more people won’t hear those allegations.
