Pelosi hosting Tony Bennett, Martin O'Malley at State of the Union

Pelosi will also host a fourth grade student and her mother, both from Newtown, Conn., the location of a shooting massacre in December. Pelosi's office announced Bennett and O'Malley on Tuesday after announcing the student and mother a week earlier. The top Democrat's office is not releasing the name of the student or mother.

The fourth-grader sent a letter to Pelosi in support of a ban on assault weapons.

"What everyone in Newtown wants, is for you to ban semi automatic weapons and large capacity magazines and to make everyone use gun safes," the letter, released by Pelosi's office, read. "This is important so that a person cannot shoot many people at once, and/or injure people badly.  Semi-automatic weapons and large capacity magazines end lives and put lives at risk. This ban will help prevent individuals, families and communities from suffering the way we are in Newtown."

A number of legislators have called for federal action to reduce gun violence in response to the Newtown shooting. Sen. Dianne Feinstein (D-Calif.) is pushing legislation that would reinstate the federal assault weapons ban. That legislation expired in 2004.

Meanwhile, Pelosi's Republican counterpart, House Speaker John Boehner (Ohio), also released his guest list for the State of the Union address. Boehner's guests include: Ted Kremer, former bat boy for the Cincinnati Reds; Jeanette Hernandez Prenger, CEO of data management firm ECCO select; American Red Cross President and CEO Gail McGovern; Washington Sacred Heart School Principal Arthur Mola, and UAW Local 402 President Jason Barlow. Boehner is also hosting Laci Joseph and Zuri Franklin, fourth grade students in the Washington, D.C.-area who won Opportunity Scholarships.
