House Republican leaders delayed a vote on the "consensus" immigration legislation Thursday afternoon as they scrambled to convince enough GOP lawmakers to support the measure.
The vote on that bill is now scheduled for Friday morning, according to multiple House GOP leadership aides.
Some GOP lawmakers felt that they didn't know what was in the "consensus" bill as it was still being tweaked hours before they were scheduled to vote on it.
