“I can’t believe it. I just heard that the worst mayor in the history of New York City, and without question the worst mayor in the United States, is now running for president," Trump said from behind a desk on the presidential plane.

"It will never happen. I’m pretty good at predicting things like that," he continued. "I would be very surprised to see him in there for a long period but it’s just not going to happen.

"If you like high taxes and if you like crime you can vote for him, but most people aren’t into that. So, I wish him luck, but really it’d be better off if you got back to New York City and did your job for the little time you have left."

Trump recorded the video message while en route to his native New York City and de Blasio's home turf. The president is scheduled to attend a fundraiser and will spend the night at Trump Tower in Manhattan.

It was reminiscent of messages Trump used to record from his desk at Trump Tower during the 2016 campaign.

The recording marked the second time Thursday Trump went after de Blasio. The president tweeted Thursday morning that the mayor is "a JOKE."

De Blasio launched his White House bid Thursday morning, becoming the 24th candidate to seek the Democratic presidential nomination. The mayor kicked off the campaign vowing to help the working class and directly attacking the president as a "con artist."

The mayor has among the lowest favorability ratings of any Democrat in the field, and 76 percent of New York City residents said in a Quinnipiac University poll released last month that he should not run for president.
