Former Homeland Security Secretary Jeh Johnson agreed on Sunday that the U.S. needs to end its catch-and-release policy at the border, and said the U.S. should continue to expand family detention centers as he did in the Obama administration.

“Without a doubt the images and the reality from 2014, just like 2018, are not pretty and so we expanded family detention,” Johnson said on “Fox News Sunday.” “We believed it was necessary at the time. I still believe it is necessary to maintain a certain capability for families. We can’t have catch and release.”
