The Senate's Gang-of-Eight immigration package cleared a last procedural hurdle on its way to final passage Thursday when lawmakers voted 68-32 to close debate.

The tally is in line with earlier procedural votes that helped advance the compromise package toward a final vote that leaders scheduled for 4 p.m. on Thursday, with all Democrats and around a dozen Republicans backing comprehensive immigration reform.

Meanwhile, House Speaker John Boehner, R-Ohio, made clear that the Senate bill, which includes a path to citizenship for illegal immigrants, is dead-on-arrival on the other side of the Capitol.

That chamber plans instead to pass smaller, narrowly focused immigration proposals dealing with border security and other policies that have broad GOP support.
