Trump made Twitter his megaphone. A fact check won't change that.

When President Donald Trump felt the need to lash out at Twitter on Tuesday, he didn't turn to Facebook or YouTube. He turned to Twitter.

The president has launched any number of insults, tirades and misleading statements from his Twitter account in recent years. But it was two tweets about voting by mail that spurred the company to take action, adding a fact check label to them.

The president fired back, tweeting that the company was "stifling FREE SPEECH" by fact checking his tweets about mail-in ballots.

But Trump's choice of Twitter as the best platform from which to attack Twitter highlights the singular appeal of the platform. As much as the president may be angry with the company, there's nothing quite like the real-time global broadcasting apparatus of Twitter, as well as the network of accounts that have been built up in recent years that amplify his statements.

And Twitter has shown a willingness to let Trump test its rules — including the president's most recent attacks on MSNBC host Joe Scarborough.
