Twitter may bring the headlines for President Trump, but Facebook is where his reelection campaign is spending millions of dollars as the 2020 race gears up. The Trump team has spent more than double what Democratic contenders combined have on Facebook ads.

Political advertising strategists who spoke to Axios say that this level of ad spend on digital platforms this early in the campaign season is unprecedented. Meanwhile, Trump announced he was going to be looking into alleged bias from tech giants while speaking at a news conference alongside Brazilian President Jair Bolsonaro Tuesday.

“Something is happening with those groups of folks that are running Facebook and Google and Twitter, and I do think we have to get to the bottom of it,” he said. “It is very fair, it’s collusive and very, very fair to say that we have to do something about it. And if we don't, you know, the incredible thing, we can win an election and we have such a stacked deck."
