Twitter CEO Elon Musk visited Capitol Hill on Thursday and met with House leaders from both parties, saying discussions centered on the social media platform he bought in October.

In a tweetMusk described the meeting with House Speaker Kevin McCarthy, R-Calif., and House Minority Leader Hakeem Jeffries, D-N.Y., as an effort to «make sure that this platform is fair to both parties.»

Musk was seen by a reporter entering the Capitol Thursday night but was not available for questions. His visit was not publicly announced in advance.

McCarthy, who turned 58 on Thursday, previously told reporters that Musk «came to wish me a happy birthday.»

When asked later if the meeting included a discussion about Twitter, a McCarthy spokesperson referred to birthday wishes.

NBC News has reached out to Jeffries’ office for comment.

Musk’s visit comes amid ongoing allegations from the Republican Party that most social media platforms are suppressing conservative voices.

Since taking over Twitter, Musk has restored hundreds of accounts of right-wing activists and QAnon supporters, according to data reviewed by NBC News.

Musk last month promoted a series of tweets in internal Twitter documents about how the company handled a news article about President Joe Biden’s son Hunter Biden in 2020 by restricting people from tweeting and direct messaging about it. McCarthy later tweeted that «the new Republican House majority will get answers for the American people and the accountability they deserve.»

Musk also announced after taking over Twitter that he would reinstate Trump’s account after he was banned for posts linked to the January 6 riots. On Wednesday, Meta, the parent company of Facebook and Instagram, announced plans to reinstate Trump’s account in the coming weeks, nearly two years after he was suspended from those platforms following the attack on the Capitol.
