COLORADO SPRINGS, Colo. (AP) -- Billionaire industrialist and conservative benefactor Charles Koch is hosting hundreds of the nation's most powerful political donors this weekend in Colorado.
The exclusive gathering at the foot of the Rocky Mountains is open to donors who promise to give at least $100,000 each year to Koch-approved groups. Elected officials are expected to attend the three-day gathering as well.
The Koch network has avoided supporting Donald Trump's presidential campaign so far, focusing its resources instead on helping the GOP maintain control of the Senate.
Charles and David Koch have hosted such gatherings of donors and politicians for years, but almost always in private. The weekend's event includes a small number of reporters, including The Associated Press.
