Republicans on House Oversight Committee on Monday called on President Obama to oust Internal Revenue Service Commissioner John Koskinen for obstructing the committee’s investigation into the tax agency’s targeting of conservative groups.
House Oversight Committee Chairman Jason Chaffetz said the committee was actively considering contempt charges and impeachment proceedings against Mr. Koskinen in the event the president does not remove him from office. 

“Mr. Koskinen should no longer be the IRS Commissioner. We have asked the president to remove Mr. Koskinen from office,” Mr. Chaffetz said at a Capitol Hill press conference, where he was joined by more than a dozen fellow Republicans form the committee.
“Mr. Koskinen failed in his duty to preserve and produce documentation to this Committee,” he said. “The IRS failed to comply with a congressional subpoena. The IRS further failed by making false statements to Congress.”
The committee’s investigation of the targeting scandal has been frustrated by the failure of the IRS to turn over email of Lois Lerner, who ran the tax-exempt-organizations unit responsible for the targeting and whose computer hard drive was destroyed.
Mr. Chaffetz said that the committee had determined that Ms. Lerners’ email could have been recovered, but backup tapes containing up to 24,000 of her email were destroyed while Mr. Koskinen gave the committee assurances that all records were being preserved and every effort was being made to locate the saved emails.
The committee released a 10-minute video outlining their case against Mr. Koskinen and the failure of the IRS to follow its own rules for preserving email records.
Rep. Elijah E. Cummings of Maryland, the top Democrat on the committee, called the resignation call a “manufactured Republican political crisis.”
“This is a strange, oddly-timed rehashing of conspiracy theories that were debunked by the Inspector General himself — who concluded in a report to the Oversight Committee just last month that there is no evidence to substantiate these claims,” Mr. Cummings said in a statement.
“The bottom-line is that the Inspector General found no evidence to back-up Republican claims of political motivation, White House involvement, or intentional destruction of evidence. Calls for Commissioner Koskinen to step down are nothing more than a manufactured Republican political crisis based on allegations that have already been debunked,” he said.
The IRS’ inspector general concluded that the agency did, in fact, target conservative and tea party groups for intrusive scrutiny, and the Justice Department is still conducting a criminal investigation into the targeting
