“I cannot think of a legitimate argument” against building a border wall, Mark Morgan, former border patrol chief for Pres. Barack Obama, said Monday in an interview with Fox News’ Tucker Carlson.

“Yes. They absolutely work,” Morgan said, when asked if walls are effective:

“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. 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.”

Morgan, who was removed from office by President Donald Trump, nonetheless, says Trump is right about the need for a wall – based on historical fact and the experience of hands-on border experts:

“The president is right. 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. 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. Why aren’t we listening to the experts, and people who do it every day? I don’t understand it, Tucker.”

Opposition to building the wall is based on personal dislike of Donald Trump, rather than on the substance of the president’s reasons for advocating it, Morgan said:
