Mark Morgan, Border Patrol chief for former President Barack Obama, told Fox News’ Tucker Carlson on Monday that physical border barriers “absolutely work” and that President Donald Trump is “right” when it comes to the southern border.

When Carlson asked Morgan, who was dismissed by the Trump administration, whether border walls work, Morgan responded: “Yes, they absolutely work.”

“If you look in the past, you don’t have to go too far back in history, that bipartisan legislation that was passed: the Secure Fence Act,” Morgan said. “In 2006 and 2012, bipartisan legislation passed where they built the wall, or fence, or physical barrier, or whatever you want to call it. It’s a wall. It works.”

“The president is right,” Morgan continued. “The other day when they had the national press conference, and they got up and they said the wall works, they’re right. And it’s not based on a personal political ideology. That’s based on historical data and facts that can be proven.”

“I believe in what the president is doing,” Morgan added. “When he says that this is a national security problem, he’s absolutely correct. And that doesn’t come just from me — that comes from professionals who have been doing this their entire adult lives, serving the country on the border, protecting the citizens. They’re saying it works.”

Morgan noted that the only reason that Democrats and the media oppose the wall is that Trump is the one advocating for it.
