Washington (CNN) -- Rep. Luis Gutierrez and 10 other people demonstrating for immigration reform were arrested Tuesday outside the White House, the U.S. Park Police and a spokesman for the congressman said.
Douglas Rivlin, the press secretary for the Illinois Democrat, said Gutierrez and the other people arrested "were sitting on the sidewalk in front of the White House after being told to leave" the protest, held to mark the more than 1 million people deported since President Barack Obama took office.
"The U.S. Park Police gave them a warning to leave. After the third warning they were put in plastic handcuffs and taken away," Rivlin said.
Park police Sgt. David Schlosser said the 11 people arrested paid a fine for disobeying an official order and were released.
Gutierrez is an outspoken advocate for immigration reform. A statement about the protest said that while Obama correctly blames Republicans for blocking immigration reform, "it doesn't get him off the hook."
The president has the power to stop deportations of undocumented immigrants "with deep roots in the United States, and we think he should use it," Gutierrez said in the statement.
