Jeh Johnson, former DHS secretary in Barack Obama's administration, called presidential candidate Julian Castro's proposal to de-criminalize illegal border crossing essentially advocacy for "open borders."
"That is tantamount to declaring publicly that we have open borders," Johnson told the Washington Post. "That is unworkable, unwise and does not have the support of a majority of American people or the Congress, and if we had such a policy, instead of 100,000 apprehensions a month, it will be multiples of that."
Other 2020 candidates, including Sens. Elizabeth Warren (D., Mass.), Kirsten Gillibrand (D., N.Y.), and Kamala Harris (D., Calif.) as well as South Bend Mayor Pete Buttigieg have embraced the proposal. Eight of the more than 20 candidates have expressed explicit support for open borders. Sen. Cory Booker (D., N.J.) said he would "virtually eliminate immigration detention," if elected president.
