A significant number of Senate Democrats voted with Republicans on Thursday to advance a GOP-led bill to require the detention of undocumented migrants charged with certain crimes – a key step that puts the legislation on the verge of passage.

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

The bill, which would impose harsher penalties on some people who are in the country illegally, is an early test of how far right Democrats could shift in the second Trump presidency.
