Republican leaders of the House Judiciary Committee on Monday accused Attorney General Eric Holder of having “something to hide,” after the Justice Department issued a formal defense of his questionable testimony on reporter surveillance — a defense Republicans rejected as inadequate.

“This response is insulting and further proof that Attorney General Holder refuses to hold himself accountable,” Rep. Jim Sensenbrenner, R-Wis., said.

Holder was facing a Wednesday deadline, set by the committee, to explain his May 15 testimony.

At the time, the attorney general said under oath he knew nothing of the “potential prosecution” of the press. Days later, it emerged that Holder was involved in his department’s successful effort to obtain Fox News reporter James Rosen’s personal emails — the DOJ sought access to the documents by arguing Rosen was a likely criminal “co-conspirator” in a leak case.
