U.S. Senator Lindsey Graham (R-S.C.) looks on during a news conference calling to designate Russia as state sponsor of terrorism, on Capitol Hill, in Washington, U.S., September 14, 2022.

The Senate Ethics Committee said Thursday that Sen. Lindsey Graham, R-S.C., violated Senate rules during a Fox News appearance last year when he requested donations for Hershel Walker's Senate campaign in Georgia.

In a letter publicly released by the panel, Democratic Chair Chris Coons of Delaware and GOP Vice Chair James Lankford of Oklahoma said Graham violated Senate rules during the Nov. 30 interview when he solicited funds in the rotunda of the Russell Senate Office building. It is against Senate rules to seek campaign donations in a federal building.
