During the ABC News interview with Chief Anchor George Stephanopoulos, Trump's Chief of Staff Mick Mulvaney coughed as Trump was giving an answer about his finances and a very disappointed Trump kicked him out of the Oval Office. It's clear that Trump did not expect ABC to air this exchange as he immediately went into TV-mode and did a "pick up" - attempting to give the same answer without the cough.
The ABC crew obliged Trump's assumption, that they would also rather air a clean answer, but what he didn't expect was that ABC would realize him getting frustrated and kicking the White House Chief of Staff out of the Oval Office was more newsworthy than more lies about releasing his finances.
Watch the in-depth interview below, which, if you can find the hilarity in the absurdity of his lies and ignorance and flat-out un-Presidential behavior, it's really entertaining. Stephanopoulos did a decent job checking and correcting Trump's attempts to gaslight.
