Paul Nehlen, the Wisconsin businessman who has launched a primary challenge to Rep. Paul Ryan, is currently touring the U.S.-Mexico border alongside Brandon Darby, the top editor of Breitbart Texas.

Nehlen accused Ryan of failing to fight for border patrol agents during his time in Washington. The Republican Speaker of the House has come under fire for pushing open-borders policies with Rep. Luis Gutierrez, going so far as to say the United States is “more than a country… [and] more than our borders.”
