Philip Bump at the Post notices Trump’s Twitter silence about Finsbury Park:

Donald Trump tweeted about the terrorist attacks in Paris in November 2015 about 3½ hours after they occurred. The following month, he tweeted about the mass shooting in San Bernardino, Calif., 90 minutes after the violence began. It took fewer than 12 hours from the time an EgyptAir flight went missing in May 2016 for Trump to speculate publicly that the attack was terror-related. More than a year later, it’s still not clear what happened to the plane.

When terrorists drove a van into a crowd on London Bridge earlier this month, Trump tweeted about the need to be “smart, vigilant and tough” even before authorities identified terror as the motive behind the attack.

But now, bupkis.

In response to a crisis, one of the simplest responses from a president is a carefully worded statement of support, condolence or outrage. Simpler still is a brief message on social media. Trump built his political career in part on his willingness to jump into any number of frays by tweeting about them. As we’ve noted in the past, he shows little reticence to tweet about things he sees on television right after he sees them. Yet, Monday morning: silence.

Trump’s use of Twitter betrays his interests and disinterests. On Sunday, Father’s Day, Trump tweeted, in order:

• A two-part defense of his political success.
• An outlier poll showing him as more popular than he is.
• A retweet of the performers Diamond and Silk criticizing the media.
• A retweet of his son critical of former president Barack Obama.
• Praise for Camp David, where he spent the weekend.
• And finally, a retweet of the White House’s “Happy Father’s Day” message that morning.

That Trump hasn’t mentioned the attacks on Muslims in London isn’t surprising, mind you. It took days for him to praise the two men who were stabbed to death in Portland, Ore., while defending Muslim women on a train. It took almost a week for him to speak out about the shooting of two Indian men in Kansas by someone who thought that they were Muslim.

He’s too stupid even to fake it for appearances’ sake.
