President Donald Trump said at a campaign rally in Arizona on Wednesday that government leakers "should be shot," NBC News and the New York Post reported. The rally was in Bullhead City, NBC News reported.

Trump was talking about what he said was a leak of the timing of last year's US strikes on Iran's nuclear sites, the outlets reported. "Somebody leaked, some sleazebag," Trump said, according to NBC News and the Post. He said details of the departure time from Missouri appeared in The New York Times and on CNN, the outlets reported.

Trump said he called off the raid after the leak, the outlets reported. The strike still went ahead, NBC News reported, and the Post reported that Trump said it went ahead two days later. "In my opinion, leakers should be shot," he said, according to the Post. "In the old days, we used to shoot leakers."

Trump called leakers "the scum of the Earth," NBC News reported. He then pointed to the journalists covering the rally. "Those same people up there, they're almost as bad as a leaker, because they leak," he said, according to NBC News.

The administration has moved to crack down on leaks to the media, NBC News reported. Federal investigators gave polygraph tests to about 50 members of the military's Joint Staff, NBC News reported, citing The New York Times. In January, Trump authorized a search of the home of a Washington Post reporter in a case involving a government contractor, NBC News reported.

The rally was meant to support Republican candidates, including Representative Andy Biggs, who is running for governor of Arizona, the Post reported. Boxer Floyd Mayweather Jr. also spoke at the event, the Post reported.

What we know: Trump said at the rally that leakers should be shot, citing the Iran strike leak.
