If Democrats retake the House, Maryland congressman Elijah Cummings will likely become the new chair of the Oversight committee. Here, a preview of what to expect from their coming investigations of the Trump administration.Cummings says President Donald Trump “is a person [who] calls a lie ‘the truth’ and the truth ‘a lie.’” He thinks the president violates the Constitution’s emoluments clause daily, and sees an abnormal tolerance for corruption and misconduct emanating straight out of the Oval Office. And, in the eyes of the 67-year-old Democrat, just as troubling is the notion that Congress has fallen flat on its Constitutional duty to check the administration’s whims.Expect that to change if Democrats retake the House in November. Then, Rep. Cummings will likely become the chairman of the House Oversight and Government Reform Committee, giving him subpoena power and the ability to call as many hearings as he wants on whichever topics he chooses. In light of everything he’s learned about Trump—and especially after Senate testimony last week by Supreme Court nominee Brett Kavanaugh, which Cummings saw as dishonest—the congressman doubts he’ll be able to believe any denial from anyone in the administration, regardless of whether or not they’re under oath, he said in an interview for POLITICO’s Off Message podcast.POLITICO's Off Message podcast is hosted by Isaac Dovere and is part of the Panoply network.
