Immigration Reform Supporters See Uphill Battle

Sen. McCain warns outside groups need to get more involved

Supporters of far-reaching immigration legislation see an uphill battle to get a bill to President Barack Obama's desk. They say outside advocates need to step up their efforts.

Republican Sen. John McCain of Arizona is a lead author of the comprehensive bill passed by the Senate last month. McCain warns that his side is not winning the fight.

He says there needs to be a concerted campaign that's so far been lacking, particularly from business and religious groups that can influence House Republicans
