Washington (CNN) A rare press briefing from a Trump administration official yielded an especially telling line about the Trump presidency: "Get over it."

President Donald Trump's acting Chief of Staff Mick Mulvaney said it after confirming the existence of a quid pro quo and offered it up as a retort , but it's essentially the Trump administration's answer to any number of issues swirling around the White House at any given time.

It has a classic Trumpian flavor, charging straight ahead no matter what the haters say, as you can see in decisions like removing troops from Syria and even hosting the G7 at Trump's own property in Florida

And there are even some members of Trump's own party who may not be able to "get over" Trump's latest maneuverings on Syria -- and even in the looming impeachment battle
