President Donald Trump tweeted Tuesday suggesting the U.S. Department of Justice is part of the so-called "deep state." Here's what that is.
The "deep state" is a conspiracy theory purporting a behind-the-scenes network of officials in the U.S. government and elsewhere are working to influence policy and delegitimize elected leadership — in this case, the Trump administration.
Trump has referenced the "deep state" on other occasions. And former White House chief strategist Steve Bannon and Fox News' Sean Hannity have promoted the conspiracy.
Trump's son Eric Trump also tweeted Tuesday suggesting Hillary Clinton, Barack Obama and Ellen Degeneres are all part of the so-called "deep state."
