(CNN) -- A new federal courthouse in Yuma, Arizona, will be named after slain federal Judge John M. Roll.
The House of Representatives unanimously approved the resolution, passed by the Senate last week, on Wednesday.
The 63-year old judge was gunned down in Tucson, Arizona, along with five others last month while he attended an event hosted by his friend U.S. Rep. Gabrielle Giffords, who was critically wounded in the attack. She is undergoing rehabilitation in Houston, Texas.
"Judge Roll lost his life trying to to protect another. His act of courage will always be remembered," Arizona Rep. Paul Gosar said on the House floor. "His outstanding character will never be forgotten."
The resolution was introduced by Arizona U.S. Sens. John McCain and Jon Kyle. Roll was appointed by President George H.W. Bush in 1991 and quickly rose to become the state's chief federal judge in 1996.
The court, still under construction, is expected to open in a few years.
A 22-year-old suspect, Jared Loughner, faces federal charges in the shootings.
