The Texas Democratic Party is calling on Sen. Ted Cruz, R-Texas, to resign or be expelled from office after the Republican lawmaker flew to Cancún, Mexico, for a family vacation in the middle of a deadly winter storm that has left millions of Texans without water and electricity.
Cruz has returned to Texas, calling the trip "a mistake."
In a statement issued Thursday, Texas Democratic Party Chairman Gilberto Hinojosa called the senator's trip to Cancún "deeply disturbing and disappointing."
