Families Belong Together demonstrators denounce family separation around America: PHOTOS

In major cities and tiny towns, marchers gathered across America, moved by accounts of children separated from their parents at the U.S.-Mexico border, in the latest act of mass resistance against President Donald Trump's immigration policies.

More than 700 planned marches drew hundreds of thousands of people across the country, from immigrant-friendly cities like New York and Los Angeles to conservative Appalachia and Indiana to the front lawn of a Border Patrol station in McAllen, Texas, near a detention center where migrant children were being held in cages.
