During an interview on CNN’s “State of the Union," Johnson called for funding that is “separate and apart” from debate over immigration policies. A shutdown of the agency would result in the furloughing of 30,000 employees, he said.
"If people in Congress want to have that debate about immigration reform, let's have that debate. But don't tie that to public safety and homeland security for the American people," he said.
Johnson said temporary measures to fund his department, such as continuing resolutions, are restricting new initiatives, including border security efforts, grants to state and local law enforcement and new Secret Service agents for the upcoming presidential election cycle.
