Newly in the minority, Democrats say they will vote with Republicans to advance legislation that would require federal authorities to detain unauthorized immigrants who have been accused of certain crimes.

The measure easily cleared the 60-vote filibuster but marked the first of likely several procedural hurdles before Republicans can declare victory.

The Senate appears to have 60 votes to begin debate on a GOP priority, with a group of Democrats backing it as the party recalibrates on immigration. Final passage is uncertain.
