Republicans signal no retreat on SAVE Act as marathon Senate debate kicks off

Senate Republicans dug in for the long haul as they embarked on their floor takeover and signaled that the hours of debate that crept well beyond the upper chamber's usual twilight business hours were just the beginning.

The GOP launched its plan to control the Senate floor earlier Tuesday and spent the ensuing hours lauding and defending the Safeguarding American Voter Eligibility (SAVE) America Act as Senate Democrats hammered the bill as a tool of voter suppression.

But without Democratic support, the bill is destined to fail.
