WASHINGTON (AP) — The Senate on Thursday overwhelmingly approved the nomination of Caroline Krass to serve as the CIA’s top lawyer amid a snooping fight pitting the spy agency against Congress and ensnaring the CIA’s acting general counsel.

The 95-4 vote came after Sen. Mark Udall, D-Colo., dropped his procedural hold on the nomination, a reflection of his frustration with the agency’s willingness to give Congress access to documents related to its detention and interrogation program during the Bush administration’s war on terror.
