Immigration Bill Test Vote

All eyes are on Capitol Hill, as the senate moves into the home stretch on the debate over immigration reform.

Senators cleared some final hurdles Wednesday; clearing the way for Thursday's vote.

The bill still includes a guest worker program and an eventual path to citizenship for millions of illegal immigrants.

However there are new additions, like tougher penalties on businesses that hire illegal workers.

Business owners will be required to use a new screening system, that would include information from the internal revenue service, social security office and homeland security department.
