Immigrant Advocates Arrested Outside White House KATHLEEN MILLER, Associated Press Writer WASHINGTON (AP) ― About 35 immigrant advocates have been arrested in front of the White House fence, including a U.S. congressman, after they sat down and defied orders from police. Protesters are usually required to stay in motion when demonstrating in front of the White House. U.S. Rep. Luis Gutierrez of Illinois was among those detained on a nearby bus. Many of those arrested Saturday held letters of a sign saying, "Obama, Stop Deporting our Families." Hundreds of protesters turned out for the rally at Lafayette Park, urging President Barack Obama to fulfill his campaign promises to achieve immigration reform. Obama was to return to the White House around 2:40 p.m. after speaking at the University of Michigan. Two Marine helicopters flew overhead, but it wasn't clear if Obama was on board.
