The proceeds from the $10 tickets will be donated to the Boys and Girls Clubs of Greater Washington, Washington Literacy Center and National Dreams Foundation.

The shooting wounded House Majority Whip Steve Scalise, R-Louisiana, two Capitol Police officers -- Crystal Griner and David Bailey -- Matt Mika, who is a Tyson Foods lobbyist, and Zachary Barth, a staffer for Rep. Roger Williams, R-Texas.

Scalise underwent a third surgery Thursday and was still in critical condition in the morning at a local Washington, D.C., hospital.
