At the last trump, will our president take to Twitter?

As military experts debated the range and lethality of North Korea’s latest and most successful launch of an intercontinental ballistic missile; on the day the Senate would vote to begin consideration of a once-in-a-generation tax reform; as two crucial federal judicial nominees tried to fight off the culture-war attacks of Sen. Dianne Feinstein, D-Calif., and the abortion lobby; where was President Trump?

Keeping himself busy with other matters on Twitter.

Most people sometimes goof off on social media when they should be working. But Trump's tweeting isn’t a matter of procrastination or picking petty battles. This is the president ignoring the difficult and pressing challenge of pressing his policy agenda forward, and instead pouring out divisive invective on subjects beyond his purview.

Specifically, the president scapegoated religious and ethnic minorities and attacked the news media, every politician's favorite foe.

Trump’s retweets on Wednesday morning were indefensible. “VIDEO: Muslim migrant beats up Dutch boy on crutches!” the first one read. “VIDEO: Muslim Destroys a Statue of Virgin Mary!” was the second one. “VIDEO: Islamist mob pushes teenage boy off roof and beats him to death!” the third.
