DANA POINT, Calif. — Seven sitting governors, six incumbent senators and two House members — all Republicans — have flown here this weekend for the Koch donor network conference.

There are 450 donors at a seaside resort here, and the network of conservative advocacy groups they fund aims to spend $889 million in advance of the next White House election.

The governors —

Wisconsin’s Scott Walker

Indiana’s Mike Pence

Illinois’ Bruce Rauner 

Texas’ Greg Abbott

Arizona’s Doug Ducey

South Carolina’s Nikki Haley

North Carolina’s Pat McCrory

The senators —

Colorado’s Cory Gardner

Utah’s Mike Lee

Nebraska’s Ben Sasse 

Alaska’s Dan Sullivan

Florida’s Marco Rubio 

Texas’ Ted Cruz 

The congressmen —

Ohio’s Jim Jordan, who chairs the House Freedom Caucus

Wisconsin’s Sean Duffy

Michigan’s Justin Amash

In addition to the elected officials, the crowd heard from presidential candidate Carly Fiorina earlier Saturday and will hear from former Florida governor Jeb Bush on Sunday.

The Washington Post is one of nine news organizations allowed in to cover the traditionally private confab, on the condition that the donors present not be named without their permission.

This post has been updated to reflect Amash’s attendance.
