President Donald Trump faced new pressure on Wednesday from his Republican allies in Congress over domestic abuse allegations against a former aide as lawmakers questioned whether his administration has properly vetted top staffers.
Republican Rep. Trey Gowdy, chairman of the House Oversight Committee, said he was investigating when the White House learned of "potential derogatory or disqualifying information" about former Staff Secretary Rob Porter.
Porter left the White House last week after two former wives said he abused them.
