Lawmakers briefed Friday by Deputy Attorney General Rod Rosenstein say they were told investigators are now also looking into whether White House officials have "engaged in a cover-up" related to the ongoing investigation into possible collusion between President Trump's campaign, his associates, and Russia, McClatchy reported. That aspect of the ongoing investigation into Trump's potential connections to Russia's election meddling was added in "recent weeks."

McClatchy reported that it's not entirely clear who will be targeted in the investigation into a potential cover-up. Reports surfaced this week that Trump apparently urged former FBI Director James Comey to drop the FBI's investigation into ousted National Security Adviser Michael Flynn, shortly after Flynn resigned following revelations he'd misled Vice President Mike Pence about his conversations with a Russian ambassador. Trump abruptly fired Comey last week.

Also Friday, The Washington Post reported that federal investigators have identified a so-far unnamed White House official as a "significant person of interest."
