Donald Trump selected Mick Mulvaney to be the acting White House chief of staff to succeed John Kelly, who resigned far ahead of his announced timetable.

Mulvaney, who runs the Office of Management and Budget in his real day job, said upon his hiring that he planned to “let Trump be Trump.” He had no intention, or so he implied, of reeling in the president while trying to prevent him from some of his more impulsive behavior.

Well, it’s being reported that Mulvaney got a serious dose of the real Donald Trump during a White House meeting with Democratic congressional leaders. The group met ostensibly to find a way to reopen the government, which has been shut down partially for three weeks.

Trump reportedly dressed Mulvaney down in front of those congressional leaders, telling him to “Stop, stop, just stop. What are you doing? You’re f***ing it all up, MIck.”

There you go. That’s Trump being Trump, per the White House chief of staff’s stated desire. Is this what he really intended when he took the job on an “acting” basis? I think not.

Don’t misconstrue me here. I don’t feel sorry for Mulvaney. He’s a grownup who likely knew about the loony bin into which he was entering when he agreed to run the White House staff.

Still, what I find astounding is that the president of the United States would (allegedly) treat the chief of staff in that fashion in front of a roomful of politicians and other staffers. Then again, given the president’s lack of decorum or dignity at any level, perhaps I shouldn’t be surprised at all!

The White House chief of staff once was considered the plum of plum jobs in D.C. No longer. Not for as long as Donald Trump is president of the United States. He’s already burned through two chiefs of staff, Kelly and before him Reince Priebus. Kelly was brought in to bring a sense of order after Priebus was canned; indeed, Priebus couldn’t control the traffic in the Oval Office, just inflaming the chaos that dictates the flow within the White House.

Now we have Mulvaney perched in the White House hot seat. I’ve thought all along that an “acting” chief of staff cannot sustain himself over any length of time. I mean, Mulvaney already has a full-time gig at OMB, which is a huge job all by itself.

So now he gets pounded and pilloried by the president while the government remains shut down.

Great work if you can get it, right, Mick?
