Facebook and Twitter immediately clamped down on Trump's posts that prematurely declared election victory, but they did so in very different ways

• Facebook and Twitter both put rules in place before the election restricting content from candidates claiming premature victory.
• In social media posts, and then in a speech on election night, President Donald Trump falsely claimed he had already won the election before the full results were in.
• Facebook and Twitter immediately labeled Trump's posts — but they did so in different ways, and the social media giants reacted differently to other claims from Trump. Here's how they reacted.

In the run-up to the US presidential election, social media giants Facebook and Twitter both said they would take action against posts from candidates that claimed premature victory.

And during remarks at the White House early on Wednesday morning, Trump did exactly that.

"We were getting ready to win this election. Frankly, we did win this election," Trump said during remarks at the White House.

The full results for the US election are not yet in.

Even before Trump made his speech, he had already signaled on both Facebook and Twitter that he'd claim victory.
