So much for that "pivot"

We should start an immediate investigation into @SenSchumer and his ties to Russia and Putin. A total hypocrite! pic.twitter.com/Ik3yqjHzsA

I sort of figured this was just Trump mouthing off; "Crazy Uncle President*," as Charlie Pierce described him.

But this one:

I hereby demand a second investigation, after Schumer, of Pelosi for her close ties to Russia, and lying about it. https://t.co/qCDljfF3wN

Does he understand he's the President?  And if he wants to start an investigation, this is not the way to do it (setting aside any veracity of the claim, which Nancy Pelosi addressed:)

.@realDonaldTrump doesn't know difference between official mtg photographed by press & closed secret mtg his AG lied about under oath. https://t.co/YRFCuJkjLA

Seriously:  does the man understand what his role is?  Does he understand how this whole "government" thing works?
