WASHINGTON—Federal agents questioned then-National Security Adviser Mike Flynn in January, shortly after the White House denied he had talked about sanctions with a Russian official, according to people familiar with the matter.
The Federal Bureau of Investigation interview, which raises the legal stakes for Mr. Flynn and adds to the political pressure on the White House, came after the president’s spokesman Sean Spicer, at a Jan. 23 news briefing, said Mr. Flynn didn’t discuss U.S. sanctions with Sergey Kislyak, Russia’s ambassador to the U.S.
At that point, U.S. intelligence officials had already intercepted conversations between the two men in which they discussed the sanctions, according to people familiar with the matter.
Mr. Flynn’s departure generated more questions Tuesday about what Mr. Trump knew about Mr. Flynn’s activities and why it took weeks for Mr. Trump to push him out.
Mr. Spicer said the president was informed about the contents of Mr. Flynn’s conversations with the Russian ambassador in late January, and White House officials spent a “few weeks” looking into the matter.
