The ranking Democrat on the Senate intelligence committee, Sen. Mark Warner, spent a couple hours Wednesday at CIA headquarters in Langley, Va., reviewing material for the committee's investigation into Russia's meddling in the election and possible contacts that Trump associates had with Russians. Other committee members, including Sens. Angus King, I-Maine, and Marco Rubio, R-Fla., also went to the CIA to read material Wednesday. Staffers on the House intelligence committee have been making trips there too to look at documents for their parallel investigation.
