Gabby Giffords is telling Washington leaders that "it's too dangerous to wait" to confront gun violence.
The former Arizona congresswoman is featured in a new television ad campaign set to air immediately before and after President Barack Obama's Tuesday night State of the Union address. In the ad, Giffords faces the camera and says that "Congress is afraid of the gun lobby."
Giffords, a Democrat, is still recovering from a brain injury suffered in 2011 when a mentally ill man shot her in the head as she met with constituents outside an Arizona shopping center. She was first lady Michelle Obama's guest at last year's State of the Union, when gun control was the emotional highlight of the president's speech.
Since then, Congress has rejected legislation to expand background checks.
