A Navy veteran and astronaut, Mark Kelly has represented Arizona in the Senate since 2020, when he won a special election to replace the late John McCain.
Kelly flew combat missions during the Gulf War as a naval aviator before being selected as a NASA Space Shuttle pilot in 1996. He flew his first space mission in 2001 as pilot of STS-108, piloted STS-121 in 2006, and commanded STS-124 in 2008 and STS-134 in 2011, the final mission of Space Shuttle Endeavour. His identical twin, Scott Kelly, is also a retired astronaut; they are the only siblings to have both traveled into orbit.
Kelly's wife, then-Arizona Congresswoman Gabby Giffords, was shot and nearly killed in an assassination attempt on January 8, 2011. Six people died in the Tucson shooting. After the Sandy Hook Elementary School shooting the following year, Giffords and Kelly founded the nonprofit Americans for Responsible Solutions, later renamed Giffords, which campaigns for gun control measures like universal background checks and red flag laws.
Kelly serves on the Committee on Armed Services, the Committee on Energy and Natural Resources, the Committee on Environment and Public Works, the Special Committee on Aging and the Joint Economic Committee.
Kelly is committed to a strong US-Israel relationship and supports a diplomatically-reached two-state solution. In 2022, Kelly, along with Senators Ossoff and Graham, successfully lobbied the Defense Department to maintain the post of United States Security Coordinator for Israel and the Palestinian Authority at a three-star general rank, which helped continue vital security coordination between Israel and the Palestinian Authority.
