MACDILL AIR FORCE BASE, Fla. — President Donald Trump on Monday accused the media of deliberately minimizing coverage of the threat posed by the Islamic State group, saying news outlets “have their reasons” for not reporting what he described as a “genocide” under way at the hands of the group.

The president did not immediately offer evidence to support his claim, made during the new commander in chief’s first visit to the headquarters for U.S. Central Command. Later, the White House released a list of 78 attacks it described as “executed or inspired by” the Islamic State group since September 2014. The White House said “most” on the list did not get sufficient media attention, although it did not explain how it defined that. Some of the incidents saw widespread attention and deep reporting.

“You’ve seen what happened in Paris and Nice. All over Europe it’s happening. It’s gotten to a point where it’s not even being reported,” Trump told a group of military leaders and troops during the visit. “And in many cases, the very, very dishonest press doesn’t want to report it. They have their reasons and you understand that.”

Trump, who has made relentless criticism of the media a hallmark of his presidency, did not explain why he thinks news outlets minimize attention on attacks.
