US President Donald Trump tweeted on Sunday night mocking Amazon CEO Jeff Bezos over his divorce, dubbing him Jeff "Bozo."

In the tweet, Trump appeared to praise the National Enquirer, the gossip tabloid that published details of Bezos' relationship with the former TV news anchor Lauren Sanchez.

Trump berated The Washington Post, which is owned by Bezos.

The Post published a bombshell report over the weekend about Trump's meetings with Russian President Vladimir Putin.

US President Donald Trump has mocked Amazon CEO Jeff Bezos over his divorce in a tweet.

In a flurry of posts on Sunday evening, Trump seemed to revel in Jeff Bezos' impending divorce from his wife, MacKenzie. The president baptized Bezos with a nickname, dubbing him "Jeff Bozo."

Previously Trump — who has been married three times — told reporters he thought the divorce was going to be "a beauty."

In his tweet Trump seems to refer to reporting by the National Enquirer, the gossip tabloid that published pictures of Bezos with the former TV news anchor Lauren Sanchez and obtained texts sent from Bezos to Sanchez.

The Enquirer is a longtime ally of Trump's, and its publisher admitted in December to having bought the rights to ex-playmate Karen McDougal's story of an affair with Trump so it could quash it using a "catch and kill" deal.

Trump has also long been critical toward Bezos, who bought The Washington Post — a publication the president has attacked over its reporting on his administration — in 2013.

The Post published an article over the weekend finding that Trump had been secretive about his meetings with Russian President Vladimir Putin, concealing details even from senior officials. Trump phoned in to Fox News on Saturday night to dispute the article, saying: "I'm not keeping anything under wraps, I couldn't care less."

The president also has a history of animosity toward Amazon, which Bezos runs as CEO. The news website Axios reported in March that Trump was "obsessed" with taking down Amazon.
