In a sternly-worded letter to Rep. Elijah Cummings — and obtained by The Daily Caller — Rep. Darrell Issa said that his House Oversight Committee is well within its rights to hold ex-IRS official Lois Lerner in contempt despite Cummings’ arguments to the contrary.

“On March 12, 2014, you sent a letter to Speaker Boehner arguing that the House of Representatives is barred ‘from successfully pursuing contempt proceedings against former IRS official Lois Lerner,’” Issa wrote. “Your position was based on an allegedly ‘independent legal analysis’ provided by your lawyer, Stanley M. Brand, and your ‘Legislative Consultant,’ Morton Rosenberg,” he wrote.

Brand and Rosenberg claimed that Lerner was not “made unequivocally certain that her failure to respond would result in criminal contempt prosecution.” But Issa strongly disagreed.

“You and your lawyers and consultants are wrong on the facts and the law,” Issa wrote. “The Facts: Lerner knew that the Committee had rejected her privilege objection and that, consequently, she risked contempt should she persist in refusing to answer the Committee’s questions.”
