For over a month, athletes across the U.S. have been sitting and kneeling during "The Star Spangled Banner" in a nod to footballer Colin Kaepernick's well-documented protest against police brutality. Now, cheerleaders are joining in on the action. The Howard University Cheerleaders knelt while the National Anthem blasted from speakers during the AT&T Nation's Football Classic at RFK Stadium in Washington, D.C. Saturday afternoon, CNN reported. Howard is one of the country's few historically black universities, with notable alums such as New York City's first African-American mayor, David Dinkins, and Congressman Elijah Cummings.
