(CBS NEWS) -- Former FBI Director James Comey met with Deputy Attorney General Rod Rosenstein last week to request more "resources, energy and attention" for the Russian investigation, a U.S. official confirmed to CBS News.

Comey then met with the two leaders of the Senate Intelligence Committee -- Sens. Richard Burr, R-North Carolina, and Sen. Mark Warner, D-Virginia -- on Monday and informed them about his request to Rosenstein.
