“There’s parts of our border which it makes absolutely no sense,” the Senate’s No. 2 Republican told a Texas ABC station on Wednesday. “But what is helpful [is] to have fencing, for example, is places like San Diego, it’s a large urban area.”
Cornyn added that he thought border security needed to include a mixture of personnel, technology and infrastructure.
“Some people want to just talk about walls or barriers, but of course unless there are people there when people come over the barrier or through it or under it, that’s not going to work, and really technology is the force multiplier here,” he said.
Border-state Republicans have increasingly voiced concerns about the feasibility of building a physical wall along the southern border.
