The first thing you see outside California Democratic Rep. Ted Lieu’s Washington office is a piece of paper taped to his nameplate that says, “Alternative Fact Free Zone, Period.”

The sign is meant to poke fun at White House Press Secretary Sean Spicer’s now infamous pronouncement about the crowd size at President Donald Trump’s inauguration and it is indicative of Lieu’s approach on social media in response to Trump’s prolific and provocative tweets.

Lieu, in his second term representing the Golden State’s deep-blue 33rd District, writes his own tweets on his personal account @TedLieu, where he regularly blasts the president’s comments.

“They want voices out there that just tell it as it is,” Lieu said of the American people. “Sometimes, I use humor because I believe in revealing truth in a way that other forms cannot. And otherwise it’s too dark all the time.”
