Former Homeland Security Secretary Jeh Johnson dismissed President Trump’s reported proposal to hire an “immigration czar” to coordinate immigration policy between federal agencies.

"We actually already have an 'immigration czar.' It's called the secretary of homeland security,” Johnson, who served during the Obama administration, quipped in an interview Monday with MSNBC.

“In 2014 when we had a spike in migration, I was very definitely the focal point of dealing with that issue, with the support of a lot of other agencies. But enforcement and administration of our immigration laws is the responsibility of the secretary of homeland security.”

The current DHS secretary is Kirstjen Nielsen.

Johnson admitted that it is sometimes necessary for someone to coordinate the agencies, such as during the Ebola crisis in 2014, but he stressed the current immigration system does not merit such person.

The Associated Press reported earlier in the day that Trump was considering former Kansas Secretary of State Kris Kobach and former Virginia Attorney General Ken Cuccinelli for a “border” or “immigration” czar position, either within the White House or at the Department of Homeland Security.

The position would work with federal agencies such as the Homeland Security Department, the Defense Department, the Health and Human Services Department, and the Justice Department to ensure all agencies are in agreement with implementing the Trump administration’s immigration policies.

Johnson also argued that withholding aid to Central American countries was the “wrong thing” to do to solve immigration challenges. The State Department announced over the weekend that it was cutting aid for three Central American countries for not doing enough to address illegal immigration at the U.S.-Mexico border.

“Cutting off aid is exactly the wrong thing to do,” Johnson said. “Work with the government of Mexico to help them secure their southern border."
