DENVER (AP) -- The mother and uncle of a teenager who was killed in the Aurora movie theater shooting are planning to attend President Barack Obama's State of the Union address Tuesday.

The Denver Post reports Theresa and Dave Hoover, who lost 18-year-old AJ Boik in the July 20 massacre, already planned to be in Washington, D.C., with the group Mayors Against Illegal Guns. Democratic Reps. Ed Perlmutter and Diana DeGette each offered their extra ticket to the president's annual address.

Since her son's death, Theresa Hoover has tried to push lawmakers for an assault-weapons ban. Proposed legislation has been introduced in the Senate and in the House by Perlmutter.

The theater shooting left 12 people dead and 70 others wounded.
