Sen. Ted Cruz flew to Cancun, Mexico, with his family this week as Texas dealt with a winter storm that as of Thursday still has left 500,000 without power, Fox News has confirmed.

Photographs of Cruz, R-Texas, at an airport began circulating on social media late Wednesday, with people alleging that the senator had left the state for Cancun amid a major crisis. A Republican source told Fox News that the allegations Cruz was traveling to the Mexican city are true.

“The photos speak for themselves,” the source said.
