The Republican senator spoke with conservative outlet Breitbart News in an interview published Monday about his plan to “enhance border security" and fund the wall by seizing billions from drug cartels over the border.

“The cartels move about $110 billion a year from the United States to Mexico,” Cassidy told Breitbart. “If we can stop that, confiscate that money, we can use cartel money to build the wall.”

" It won’t be the Mexican government, it’ll be the Mexican cartels [paying for the wall], and that’s probably the better party to build it," Cassidy added.

Back in February, Cassidy introduced an amendment to the Internal Revenue Code that would allow "the use of illicit drug trafficking proceeds to pay for physical barriers, tactical infrastructure and technology in the vicinity of the United States border."

Cassidy suggests issuing bonds that would be overseen by the attorney general, Department of Homeland Security and the Treasury in order to fund the crackdown on cartel money laundering. The senator added that the bonds would be repaid "with money seized from and forfeited by drug traffickers moving illicit profits across the southern border."

Trump pledged to build a border wall during his 2016 presidential campaign and has said repeatedly that Mexico would fund it. He has also demanded that Congress approve funding to build the wall in the spending package in September.
