WATCH: Angry Ted Cruz couldn't stop fighting with the moderators when he was cut off for time

Sen. Ted Cruz (R-TX) had a hard time keeping his temper in check during the Texas Senate debate Tuesday.

It began when Cruz and O'Rourke debated immigration and Cruz cut in to give a rebuttal despite the debate agree that he already had an opportunity for a response.

Ironically, at the end of the debate, Cruz talked about civility in politics, even after the moderator asked why he couldn't pay O'Rourke a compliment at their first debate in Dallas.

Cruz said that he truly endeavors to bring back civility, but he moved on to parrot GOP talking points calling Democrats a "left-wing mob."
