Mick Mulvaney shoved both feet into his pie hole while appearing on “Fox News Sunday.”

The show’s host, Chris Wallace, was questioning the acting White House chief of staff about Donald Trump’s lame-brain notion of bringing the G7 summit of industrialized nations to his Trump Doral National Country Club.

Mulvaney then sought to persuade Wallace that Trump “still sees himself as being in the hospitality business.” Wallace replied that Trump is “the president of the United States.”

Mulvaney answered that is Trump’s “background.”

Holy cow, man! In what world is Trump’s chief shill, the chief of staff, living?

Donald Trump sought for a brief period of time to violate openly the U.S. Constitution’s Emoluments Clause, the Article I provision that prevents presidents from profiting during their time in office. Trump would have profited handsomely by hosting the G7 summit. He got a huge amount of resistance from Congress; then he backed away from his idiotic notion.

Trump’s idiocy has nothing to do with his believing he is still in the “hospitality” business. It has everything to do with his ignorance of the office to which he was elected.

Mick Mulvaney mirrors his boss’s ignorance. He doesn’t know what he’s talking about .
