House speaker Kevin McCarthy faces next battle over new rules package

Some Republicans indicate they may withhold support unless details of concessions made to hard-right lawmakers are unveiled

After five days of chaos and 15 rounds of floor votes, newly elected Republican House speaker Kevin McCarthy is set to face an instant challenge on Monday as the House votes on a new rules package.

A handful of establishment Republicans indicated on Sunday they may withhold their support for the rules unless more details of concessions made to ultraconservative lawmakers during a week of torrid negotiations are unveiled.
