Ted Cruz, speaking now about his Cancún trip, says he began to have regrets right as he got on the plane.

He says he understands why people are upset with him.

Ted Cruz says there needs to be “a serious inquiry” into why the electrical grid in Texas was unable to meet the state’s needs.

Cruz says his thinking in going to Cancun was: “I was taking care of my family the way Texans all across the state were.”

He adds: “It was obviously a mistake and in hindsight I shouldn’t have done it. I was trying to be a dad.”

Ted Cruz says his daughters were cold and wanted to leave town: “When you’ve got two girls who’ve been cold for two days and they haven’t had heat or power and they’re saying ‘Hey look, we don’t have school, why don’t we go — let’s get out of here.’”
