Donald Trump took to social media on Sunday to congratulate himself just hours after a gunman attacked a gay nightclub in Orlando, Florida, leaving 50 dead and 53 injured.

With reports swirling that suspected shooter Omar Mateen may have had ties to Islamic extremism, Trump wanted to make clear the significance of that development: He was right.

Appreciate the congrats for being right on radical Islamic terrorism, I don't want congrats, I want toughness & vigilance. We must be smart! — Donald J. Trump (@realDonaldTrump) June 12, 2016

Almost an hour later, he posted a similar message to Facebook for good measure.

In December, following a mass shooting by a Muslim husband and wife in San Bernardino, California, Trump called for a ban on all Muslims entering the United States. Trump has since walked that proposal back, calling it a "suggestion," but maintained that we have to "find out what's going on" with regard to radical Islam.

His supporters have apparently wasted no time telling him that the massacre in Orlando is further proof that he was right to call attention to Islamic terrorism, even if his proposed Muslim ban would have had no effect in this case. Mateen, who died during the attack, is a U.S. citizen, born in New York.

Still, it seems safe to assume we'll be hearing a lot more from Trump in the coming days about how this incident supposedly meshes with his presidential campaign.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
