WASHINGTON -- Immigration reform advocates bundled up and headed to the White House on a chilly Thursday night, standing outside to support President Barack Obama as he announced relief for millions of undocumented immigrants. A small crowd began gathering about an hour before the president's prime-time address, with many members from pro-immigration reform groups like United We Dream and the Center for Community Change. As Obama spoke, people huddled in groups and watched the address on iPads and iPhones.
