The formal introduction of a bipartisan Senate Immigration bill is sparking intense debate on Capitol Hill and beyond, as lawmakers and groups on all sides digest the 844-page legislation to enact sweeping changes to the nation's immigration laws. 

Some Republicans criticized the bill as amnesty, while some groups on the left said it was unnecessarily punitive. 

Bristol County Sheriff Tom Hodgson is attending an immigration conference in Washington. 

Hodgson tells WBSM News, he's glad Congress is taking up the issue, but beleives the bill needs a lot of work......

 President Barack Obama says the bill is a compromise that doesn't give anyone everything they want _ including him. But he urges the Senate to move it forward.

A hearing is set for Friday.
