This weekend was powerful. In nearly 750 U.S. cities, including 11 in Tennessee, hundreds of thousands of us took to the streets to demand that families be together and free. The incredible mobilization came in response to the president's unconscionable decision to separate more than 2300 children from their parents at our southern border. We marched to end the zero tolerance policy, to say loud and clear that the solution to family separation cannot be family detention, and that the administration must immediately reunite the separated families. We've got to keep the pressure on, but we must demand more than the unity of families.
