Fox Nation host Tomi Lahren visited the border in San Diego, California, where she spoke with Chief Border Patrol Agent Rodney Scott about the effectiveness of border walls.

Lahren's trip to the southern border was part of a five-part Fox Nation special presentation, where she spoke with U.S. Customs and Border Protection agents about President Trump's call for a wall and the methods they use to secure the area.

Scott said that even if migrants build a ladder tall enough to scale a border wall, the time taken for them to go up and descend thereafter slows them down.

He said that the average person begins to feel "queasy" after climbing up about 18 feet, and that they no longer want to climb higher.

"That gives my agents a chance to respond," he said. "And that person just exerted a lot of energy. They're a little bit slower than they were before which makes them easier to catch."

Lahren said Wednesday on Fox & Friends that while in San Diego, she took a tour of wall prototypes with Scott and discussed the benefits of a wall.

"Why Maxine Waters and Nancy Pelosi think that they know better than someone like Chief Rodney Scott really baffles me," she said.

Tuesday in Los Angeles, Rep. Maxine Waters (D-Calif.) said that those in support of a border wall aren't "patriots."

"They're not people who love this country, they're not people who stand up for what's right," Waters said.

Lahren countered by asking what could be more patriotic than defending and securing the border to protect the country.

"People like Maxine Waters, Nancy Pelosi, Kamala Harris, they do a lot of talking about the wall, and the immorality of a wall, but what they still haven't explained is how they know more about border security than the Border Patrol agents who work to protect and defend our country for a living," she said.
