Twitter Inc. on Thursday temporarily restricted U.S. President Donald Trump's election campaign account from tweeting, saying a video from the account about Democratic presidential candidate Joe Biden's son violated its rules.

The video posted by the @TeamTrump account referred to a New York Post story from Wednesday that contained alleged details of Hunter Biden's business dealings with a Ukrainian energy company and said the former vice president had met with an adviser of the company.

"Joe Biden is a liar who has been ripping off our country for years," the video was captioned.

Twitter said the video violated its rules against posting private information, adding the account may need to delete the post in order to continue tweeting.

"It's going to all end up in a big lawsuit and there are things that can happen that are very severe that I'd rather not see happen, but it's probably going to have to," Trump said, when asked about the move by Twitter.

Twitter said Wednesday the Post story violated its "hacked materials" policy, which bars the distribution of content obtained through hacking that contains private information or trade secrets, or puts people at risk of physical harm.

Facebook Inc. and Twitter took proactive steps on Wednesday to restrict the dissemination of the Post story in the hours after it was published.

Twitter had placed similar restrictions on the account of White House Press Secretary Kayleigh McEnany on Wednesday, after she shared the Post story.
