Here is a list of key concessions and promises McCarthy and his allies have made over the course of the negotiations, based on CNN reporting:

Any member can call for a motion to vacate the speaker’s chair – this is significant because it would make it much easier than it is currently to trigger what is effectively a no confidence vote in the speaker. Conservatives pushed hard for this, while moderates are worried it will weaken McCarthy’s hand.

A McCarthy-aligned super PAC agreed to not play in open Republican primaries in safe seats

The House will hold votes on key conservative bills, including a balanced budget amendment, congressional term limits and border security

Efforts to raise the nation’s debt ceiling must be paired with spending cuts. This could become a major issue in the future when it is time to raise the debt limit to avoid a catastrophic default because Democrats in the Senate and the White House would likely oppose demands for spending cuts

Move 12 appropriations bills individually. Instead of passing separate bills to fund government operations, Congress frequently passes a massive year-end spending package known as an “omnibus” that rolls everything into one bill. Conservatives rail against this, arguing that it evades oversight and allows lawmakers to stick in extraneous pet projects.

More Freedom Caucus representation on committees, including the powerful House Rules Committee

Cap discretionary spending at fiscal 2022 levels, which would amount to lower levels for defense and domestic programs

Seventy-two hours to review bills before they come to floor

Give members the ability to offer more amendments on the House floor

Create an investigative committee to probe the “weaponization” of the federal government

Restore the Holman rule, which can be used to reduce the salary of government officials

McCarthy elected House speaker after days of painstaking negotiations and failed votes
