Sen. Ted Cruz, R-Texas, mocked Rep. Beto O’Rourke, D-Texas, for dodging questions Tuesday night about what the federal government should do to boost border security, and said the Democrat trying to win his Senate seat would prefer to tear down barriers that keep Americans safe.

The two Texas lawmakers faced off in San Antonio, where O’Rourke was asked what border security measures he would try to impose short of the border wall that he opposes. But O’Rourke replied by saying only that he has worked to boost security at official ports of entry, not outside those ports where illegal immigrants routinely try to cross.
