What did Donald Trump do today?

Not what he said you should be doing today.

In the Martin Luther King, Jr. Day proclamation he signed on Friday, Trump called on Americans to "observe this day with acts of civic work and community service in honor of Dr. King’s extraordinary life.”

Trump, who spent the long weekend at his Florida vacation home, observed the day with a round of golf in the morning and a plane ride back to Washington. He had no public activities.

Many Americans work on federal holidays, of course, and many have child care or other responsibilities that might prevent them from attending events today. But since the holiday was established in 1983, every president before Trump has spent the day engaged in service activities, or at least given a public speech.

Trump, whose first appearance on the public scene in the 1970s was as a defendant in a racial discrimination lawsuit, said last week that African countries were “shitholes.” On Sunday, he once again repeated his often-made claim that he is “the least racist person ever."

Why is this bad?

• It’s bad to demand that other people do good works you can’t be bothered to do yourself.
• Saying “I am the least racist person” inspires about as much confidence as saying “I am a very stable genius,” and for the same reasons.
