National Republican Senatorial Committee Chairman John Cornyn (Texas) on Wednesday announced that former Veterans Affairs Secretary Jim Nicholson will serve as a co-chairman of the committee’s Majority Makers program for high-dollar donors.

The program, which is currently led by Senate Minority Whip Jon Kyl (Ariz.) and Sen. Pat Roberts (Kan.), focuses on donors who give the maximum of $30,400 to the committee each year.

Nicholson is a retired Army colonel who served in George W. Bush’s Cabinet and also was chairman of the Republican National Committee from 1997 to 2001.

“I know that Secretary Nicholson’s proven leadership and experience will be invaluable as we continue expanding our fundraising efforts, building our donor base, and strengthening a critical program that has been ably led by my Senate colleagues, Jon Kyl and Pat Roberts,” Cornyn said in a statement Wednesday morning. “Thanks to the assistance from Secretary Nicholson, my Senate Republican colleagues, and our generous supporters across America, I am confident that the NRSC will have the critical resources that we need to succeed this November.”
