There are 16 states that currently have National Guard troops employed at the Southwest border to support the Department of Homeland Security's enforcement mission, a National Guard spokesperson confirmed to Axios.

The backdrop: This week, several U.S. governors announced that they were either recalling their National Guard units back from the border or vowing not to send them in the wake of the controversy surrounding the Trump administration's "zero-tolerance" policy and the separation of migrant families.
