Jason Reed / Reuters Though overshadowed by the historic debate on health care taking place nearby, local FOX news affiliate WTTG is reporting 500,000 people attended today’s immigration rally in the National Mall. Speaking by video to the crowd, President Barack Obama said he would do "everything in my power" to get a bipartisan deal within the year. "You know as well as I do that this won’t be easy, and it won’t happen overnight," Obama added. "But if we work together across ethnic, state and party lines, we can build a future worthy of our history as a nation of immigrants and a nation of laws."
