The White House has been surrounded by journalists demanding answers about FBI Director James Comey, the president's legislative agenda is going up in flames, and his approval numbers are plummeting to new lows. In short, Trump has his back against the wall.

But somehow the president's staff still finds time to push back against little slights with even pettier responses. White House social media director Dan Scavino made sure of that the other day, sniping at Ohio Gov. John Kasich.

Though likely baseless, that jab is nevertheless enlightening.

Trump probably signed off one way or another before Scavino's sent the Tweet, as Axios Jonathan Swan first pointed out. So why would one of Trump's closest advisors go after a sanctimonious governor during the middle of a crisis? Because no slight is too small to go unnoticed by the president.

Kasich's currently plugging his book and thumbing his nose at a president fighting for his political life. Though beset by enemies on all sides, Trump still finds a free hand to hit back.
