In standing in the way of Todd Blanche, President Trump's choice for attorney general, a liberated Senator John Cornyn is wielding his leverage during the lame-duck session.

The Texas Republican has emerged as a key obstacle to Blanche's confirmation, using his position on the Senate Judiciary Committee to slow the nomination process. Cornyn's resistance reflects growing tension between establishment Republicans and the incoming administration's more controversial picks.

As a senior senator with deep institutional knowledge, Cornyn understands the procedural tools available to delay or derail nominations. His willingness to challenge Trump's selection signals a potential shift in Senate dynamics, where traditional confirmation deference may no longer be automatic.

The standoff highlights the unpredictable nature of the transition period, when outgoing senators face fewer political constraints and can exercise independent judgment on lifetime appointments.
