U.S. Sens. John McCain and Jeff Flake have asked the Interior Department to support the establishment of a permanent memorial for the victims of the 2011 shootings in Tucson.
The two Republican senators from Arizona sent a letter Wednesday to Department of Interior Secretary Sally Jewell.
They say a permanent memorial also would convey the Tucson community's spirit of solidarity in the face of the horrific event.
Arizona congresswoman Gabrielle Giffords was among 19 people shot by a gunman during a constituent meeting in a supermarket parking lot on Jan. 8, 2011.
Six people died including a federal judge, a 9-year-old girl and one of Giffords' staffers.
Giffords was critically wounded after being shot in the head and had to leave office.
The gunman is serving a life prison sentence.
