Spying Spat Stalls CIA Nominee

The CIA and a Senate committee are currently in a back-and-forth over alleged spying by the agency.

The fight between the CIA and the Senate Intelligence Committee has claimed a new victim.

Sen. Mark Udall, D-Colo., is placing a hold on Caroline Krass's nomination to be the intelligence agency's top lawyer, Udall's office told NBC News.

The two sides are feuding over allegations that the CIA hacked computers used by Intelligence Committee staffers as they worked on a long-anticipated report about the agency's interrogation tactics. Committee Chairwoman and California Democrat Dianne Feinstein said Tuesday from the Senate floor that the she believes the alleged activities might have violated the Constitution. CIA Director John Brennan has denied Feinstein's accusations.

And Krass told members of the committee last year during her confirmation hearing that Congress shouldn't be given access to documents that oversee CIA activities, including its controversial drone program.

NBC News didn't elaborate on why Udall is placing the hold, and his office didn't immediately respond to requests for comment.
