California Democratic Senator Dianne Feinstein is set to introduce a bill that would end the Trump administration’s practice of separating immigrant children from their parents. The legislation comes less than a month after Attorney General Jeff Sessions made this threat to migrants crossing the U.S.-Mexico border.

Attorney General Jeff Sessions: “If you are smuggling a child, then we will prosecute you, and that child may be separated from you, as required by law.”

Since then, reports of babies torn from their mothers’ arms by ICE officers have drawn outrage and widespread calls for an end to the practice. Today, the ACLU, National Domestic Workers Alliance and other groups have called a nonviolent national day of action for children; they’re planning protests in at least three dozen cities across the United States.
