U.S. Sens. Jeff Flake (R-Ariz.), John McCain (R-Ariz.), and Ron Johnson (R-Wis.) – chairman of the Senate Homeland Security and Governmental Affairs Committee – introduced the Boots on the Border Act. The legislation would help address hiring shortfalls at Customs and Border Protection (CBP) by waiving onerous and duplicative CBP polygraph hiring requirements for applicants with qualifying law enforcement or military experience.
