That was a brief respite from the calls for “unity” in the wake of that terrible shooting in Alexandria, Va.

U.S. House Speaker Paul Ryan and U.S. House Minority Leader Nancy Pelosi sat together and pledged to put bitterness aside. They sought to honor wounded colleague Steve Scalise, the GOP House whip.

Democrats and Republicans prayed together after their charity baseball game Thursday. They hugged each other. Democrats won the game and then gave the trophy to Scalise, who is recovering from his serious gunshot wound.

All is good, yes? Hardly.

Now comes the Republican in Chief, Donald J. Trump, who launched a Twitter tirade. He wonders why Hillary Clinton isn’t being investigated; he calls special counsel Robert Mueller’s investigation into the president’s connection with Russian government officials a “witch hunt.” Indeed, he calls it the worst witch hunt in American political history.

And to think he did that while calling for “unity” in a recorded message delivered before the start of the charity baseball game.
