House Majority Whip Steve Scalise, R-La., remains hospitalized after multiple surgeries in the wake of Wednesday's shooting in Alexandria, Va., during a morning baseball practice for Republican members of Congress.
Scalise joins a long list of members of Congress shot while in office:
Rep. Gabrielle Giffords - Jan. 8, 2011
Giffords, D-Ariz., was shot and critically wounded while meeting with her constituents in a supermarket parking lot in Tucson, Ariz., by 22-year-old Pima Community College student Jared Loughner. Loughner killed six people and wounded 12.
Giffords and her husband, former astronaut Mark Kelly, created the Americans for Responsible Solutions PAC, "to encourage elected officials to stand up for solutions to prevent gun violence and protect responsible gun ownership."
In response to the shooting of Scalise and four others Wednesday, Giffords wrote a piece published in The Washington Post, and tweeted: "May we all come together with prayers for the survivors, love for their friends and family, and the courage to make this country its best."
Rep. Leo Ryan - Nov. 18, 1978
Ryan, D-Calif., was shot and killed while boarding an airplane leaving Jonestown, Guyana, by members of The Peoples Temple, a religious cult. Four other people were killed and one, 28-year-old Ryan aide Jackie Speier, was shot five times and critically wounded. Speier has served as a Democratic member of the House of Representatives since 2013, and advocates for stricter gun laws.
Sen. John Stennis - Jan. 29, 1973
Stennis, D-Miss., was shot and critically wounded outside his home in Washington, D.C., during a botched robbery.
Sen. Robert Kennedy - June 6, 1968
Kennedy, D-N.Y., was shot in Los Angeles on the night of the California Democratic primary, after claiming victory in an address to supporters. He died the next day. The assassin, Sirhan Sirhan, remains in prison.
Before his election to the Senate, Kennedy was the 64th U.S. attorney general, serving under his older brother, President John Kennedy, and President Lyndon Johnson.
Kennedy is buried in Arlington National Cemetery near his brother. Following his assassination, the rest of the 1968 presidential candidates were put under protection by the Secret Service after Congress changed the agency's mandate to include their protection.
Reps. Clifford Davis, Alvin Morel Bentley, Benton Franklin Jensen, George Hyde Fallon and Kenneth Allison Roberts - March 1, 1954
Michigan Rep. Bentley, Iowa Rep. Jensen — both Republicans — and Tennessee Rep. Davis, Maryland Rep. Fallon and Alabama Rep. Roberts — all Democrats — were shot on the House floor when three Puerto Rican nationalists opened fire from the visitors' gallery. All five members recovered from their injuries.
Sen. Huey Pierce Long Jr. - Sept. 10, 1935
Long, D-La., was shot in the State Capitol in Baton Rouge and died two days later. Long had previously served as Louisiana's governor and had announced plans to run for president.
Long was shot by Carl Weiss, the son-in-law of one of his political rivals. Long's last words were said to be, "God, don't let me die. I have so much to do."
