Congressman Darrell Issa, head of the House Oversight and Government Reform Committee, drew a line in the sand today with the head of the IRS, Daniel Werfel over the House investigation of IRs targeting of conservative groups seeking nonprofit status.

California GOP Rep. Darrell Issa, chairman of the House Oversight and Government Reform Committee, warned acting IRS chief Daniel Werfel that if “the IRS continues to hinder the committee’s investigation in any manner, the committee will be forced to consider use of compulsory process.”

Issa did not elaborate on exactly what steps his panel’s Republican majority may be prepared to take, though he noted that impeding congressional investigators could result in a prison term of up to five years.

“Obstructing a congressional investigation is a crime,” Issa stressed in a letter co-signed by Rep. Jim Jordan, R-Ohio.

In other words, it’s well past time to turn over the documents.
