House Oversight Committee Chairman Trey Gowdy suggested Sunday that certain advisers who have consulted President Trump on Russia should consider resigning.

Nearly a week ago, Trump sparked outrage among Republicans and Democrats over his private meeting with Russian President Vladimir Putin in Helsinki and his comments during a follow-up joint press conference during which he cast doubt on the U.S. intelligence community assessment that the Russian government led a campaign to meddle in the 2016 election. Under pressure, Trump made a rare omission of fault, saying he misspoke when he said did not see why Russia would have meddled in the U.S. electoral process. He even went so far as to say that he holds Putin personally “responsible” for meddling in the U.S. electoral process as a leader of the Russian people.
