Senate Minority Leader Mitch McConnell (R-Ky.) said Tuesday morning that the White House needs to answer questions about what -- if any -- role it played in the IRS's targeting of conservative groups.

“What we don’t know at this point is whether it jumped the fence from the IRS to the White House," McConnell said on the Senate floor, according to a transcript. "But we do know this: We can’t count on the administration to be forthcoming about the details of this scandal — because so far they’ve been anything but."

McConnell called for the administration to answer any and all questions related to the scandal.

Republicans have criticized the administration's cooperation in the Benghazi investigation, suggesting that the White House has prevented some witnesses from testifying and hasn't been completely forthcoming with its disclosure.

“So, this morning, I’m calling on the president to make available, completely and without restriction, everyone who can answer the questions we have as to what was going on at the IRS, who knew about it, and how high it went," McConnell said. "No more stonewalling, no more incomplete answers, no more misleading responses, no holding back witnesses, no matter how senior their current or former positions — we need full transparency and cooperation."

McConnell noted that the Obama Administration had said that the IRS wasn't targeting conservative groups.

“Despite repeated assurances from the Obama Administration that it was not targeting its political enemies through the IRS during the last election cycle, we’ve now learned that the IRS was in fact singling out conservative groups – groups who dared to speak up and express their First Amendment rights."
