Senate Majority Leader Mitch McConnell (R-Ky.) is under pressure from conservative colleagues and outside groups to change the Senate’s rues to ensure a quicker pace on Trump’s court picks.

Sens. Ted Cruz (R-Texas), Steve Daines (R-Mont.) and Ron Johnson (R-Wis.) all want to change the rules with a simple majority vote — a tactic known as the “nuclear option” because it is so controversial.

But moderates such as Sen. Lisa Murkowski (R-Alaska) aren’t comfortable with using the maneuver because it will further inflame partisan passions in the chamber.
