Eric Chaffetz is leaving no stone unturned as he purses IRS Commissioner who lied under oath, Koskinen.

The chairman of the top House investigative panel introduced a measure Wednesday to censure IRS Commissioner John Koskinen — and remove him from office without a pension — in the latest bid by Republicans to pressure him into being more cooperative in their probe of the 2013 IRS targeting scandal.

Rep. Jason Chaffetz, head of the House Oversight and Government Reform Committee, is seeking Koskinen’s resignation or removal for what he calls an alleged “pattern of conduct inconsistent with the trust and confidence placed in him as an officer of the United States.”

If censured, Koskinen, who became commissioner in 2013, would also forfeit his government pension and other federal benefits.
