Washington, DC (WHBL- KFIZ) - Congressman Glenn Grothman and other members of the House Oversight and Government Reform Committee are encouraging the president to remove IRS Commissioner John Koskinen. It has to do with Koskinen’s alleged obstruction into Congressional investigations on the IRS’s targeting of conservative groups. Grothman says if the president doesn’t remove Koskinen they could impeach the IRS Commissioner or vote him in contempt of Congress.
