Cleopatra Pendleton, mother of slain teen Hadiya Pendleton, is featured in a public service announcement for gun control.
The PSA was made by Mayors Against Illegal Guns, a bipartisan coalition which includes Chicago Mayor Rahm Emanuel.
In the PSA, Pendleton asks viewers to "tell Congress to support commonsense reforms so no more innocent children are killed."
The announcement comes just after Cleo Pendleton and her husband Nate Pendleton attended President Barack Obama's State of the Union address as guests of First Lady Michelle Obama.
Obama's address mentioned Hadiya Pendleton's death and called for gun reforms after he announced a package of executive actions and proposals aimed at reducing gun violence last month.
"One of those we lost was a young girl named Hadiya Pendleton. She was 15 years old. She loved Fig Newtons and lip gloss. She was a majorette. She was so good to her friends, they all thought they were her best friend. Just three weeks ago, she was here, in Washington, with her classmates, performing for her country at my inauguration. And a week later, she was shot and killed in a Chicago park after school, just a mile away from my house," he said.
The President also mentioned the young teen's death in his gun violence speech at Hyde Park Academy High School Friday.
He said stricter gun laws could help stem the "mindless violence" that plagues cities around the country. And he called for more initiatives to improve communities and strengthen families.
Shortly after his speech, an 18-year-old woman was shot and killed. Her sister was at Obama's event.
