Trump, without offering any evidence, reiterated his accusations of political bias by such technology platforms, tweeting: "Republicans feel that Social Media Platforms totally silence conservatives voices. We will strongly regulate, or close them down, before we can ever allow this to happen."
He added: "Clean up your act, NOW!!!!"
Representatives for Twitter and Facebook could not be immediately reached for comment on Trump's tweets. Shares of the companies were down in pre-market trading following his posts.
In the pair of early morning posts, the Republican president again blasted mail-in ballots. Trump posted similar tweets about the ballot topic on Tuesday, which had moved Twitter to add a blue exclamation mark alert underneath those tweets to warn his claims were false and had been debunked by factcheckers.
The dramatic shift by the tech company, which has tightened its policies in recent years amid criticism that its hands-off approach has allowed misinformation to thrive, had prompted Trump to accuse it of interfering in the upcoming U.S. presidential election.
