U.S. Rep. John Lewis was arrested Tuesday in front of the Capitol during a protest advocating reform of the nation’s immigration laws.

The Atlanta Democrat was one of several members of Congress arrested along with other protesters at the culmination of a march up the National Mall, as they locked arms and refused to move from the street.

It was the 45th time Lewis, a major figure in the civil rights movement, has been arrested in acts of civil disobedience, according to a spokeswoman.
