A Democratic lawmaker collapsed during a rally Wednesday in Washington, D.C., where several left-wing grassroots activists mixed with politicos to protest the Trump administration’s policy which allows the parents of illegal immigrants to be separated from their children born in the U.S.

Rep. Joe Crowley, D-N.Y., fell on the street in front of the U.S. Customs and Border Protection building, according to a CNN journalist, after protesters chanted, “Until they arrest us, we will stay here, however long it takes.”
