Until recently, Senate Republicans had routinely approved Trump's nominees for lifetime seats on district and appeals courts during his second term, confirming 57 so far and helping him cement a conservative imprint on the judiciary that will outlast his presidency.

But as the White House and Senate Republican leaders press ahead with judicial nominees during the lame-duck session, a handful of Republicans have blocked or cast doubt on three nominees selected for their home states.
