Patrick Leahy Tells Eric Holder Senate Judiciary May Subpoena Targeted Killing Memos

WASHINGTON -- The Senate Judiciary Committee may subpoena the memos that the Office of Legal Counsel prepared on the Obama administration's targeted killing program, Sen. Patrick Leahy (D-Vt.) told Attorney General Eric Holder on Wednesday.

"We talked about the Office of Legal Counsel memos, I have been asking about that for some time. You and I had discussions about this. I realize the decision is not entirely in your hands," Leahy said. "It may be brought to head with subpoena... from this committee."

Holder told the committee that a drone strike against an American citizen within the U.S. would be "entirely, entirely hypothetical." Holder said there would be "a greater degree of comfort" if the American public was able to see the OLC memos for themselves and indicated that there would be a greater effort of transparency from the administration in the near future.

"I think there is a greater need for transparency," Holder said. "We are struggling with how to do that."
