Many of us have, on one or more occasions, harmed ourselves with a tweet. But most of us are not the president.

President Trump too often uses Twitter to stream his thoughts directly to the world. Some of his supporters revel in the news media and other critics. This trollish appreciation misses the main consequence, that Trump imperils his own agenda, much of which we agree with, when he tweets from the hip.

"[T]weets on legal matters seriously undermine Admin agenda and POTUS," wrote respected Republican attorney George Conway, husband of Kellyanne Conway, the councilor to the president. He continued, "and those who support him, as I do, need to reinforce that and not be shy about it."

Conway is right, and early on the morning after the London Bridge terrorist attack, in a span of 14 minutes, Trump rattled off a series of tweets that demonstrated his potential and actual self-harm.

"We need to be smart, vigilant and tough," he wrote to start the tweetstorm. "We need the courts to give us back our rights. We need the Travel Ban as an extra level of safety!"
