The Alaska Republican said the country needs an Attorney General who will "check the worst impulses of this administration," adding that she doesn't have confidence that Todd Blanche can achieve that.

The Senate Judiciary Committee voted along party lines to advance Todd Blanche's nomination for attorney general.

GOP Sens. Cassidy and Murkowski met with acting AG Blanche as they weigh whether to support his nomination to serve as attorney general, sources told ABC News.

The Alaska senator announced she will be voting no.
