A longtime personal aide to the president, McEntee was sacked from the White House on Monday over an investigation led by the Department of Homeland Security into "serious financial crimes", according to CNN.
McEntee was present by Trump's side on a near constant basis.
Mr. McEntee was removed from the White House grounds on Monday afternoon without being allowed to collect his belongings, a White House official said. The alleged crimes are said to not be related to Trump. "The White House's ongoing obstruction of congressional oversight appears to be an attempt to hide from the American people pervasive and widespread dysfunction inside the White House, which directly threatens our nation's security".
His swift departure comes amid a series of security clearance issues in the White House. Aides said that Mr. McEntee often tried to keep hangers-on away from Mr. Trump when he traveled to his Mar-a-Lago estate in Florida.
The top Democrat on the House Oversight Committee, Rep. Elijah Cummings of Maryland, asked the White House on Tuesday for more details and documentson the administration's process for vetting McEntee and others.
