Ted Cruz has announced he's running for president on Twitter.

Early Monday morning, the Republican Texas Senator revealed his bid on the social media platform.

Cruz, 44, made headlines in 2013 when he read a passage from Dr. Seuss' Green Eggs and Ham while on the Senate floor. The Senator is expected to make a more traditional announcement on Monday night at Liberty University in Virginia. He's the first person to officially announce their candidacy for the 2016 election.
