CNN — The gun control debate has escalated following the Senate's rejection of extended gun background checks on Wednesday, and celebrities like Paul McCartney have joined the discussion.
The music legend has recorded a voice message as part of Tony Bennett's Voices Against Violence, which aims to curb gun violence with tougher legislation.
When U.S. callers text "MYVOICE" to 877877, they'll hear McCartney's recording before being connected to their local senate office.
"In a minute you'll be connected to a Congressperson who needs to hear your voice now," McCartney says in his greeting. "Tell the Congressperson that you support common-sense laws that keep guns out of the hands of the wrong people, including criminal background checks on all gun sales. Enough is enough. Please add your voice ... to end gun violence."
Along with McCartney, stars like Alec Baldwin, Gloria Estefan and Josh Groban have also joined the campaign. But the star power didn't make an impact Wednesday, as proposals to expand background checks on sales of firearms and to ban some semi-automatic weapons modeled after military assault weapons failed to win Senate approval.
On Twitter, Bennett is still encouraging Americans to text Voices Against Violence to get in touch with senators.
"The Senate voted against background checks, ignoring the will of the American people. We will not stop until our voices are heard," he posted.
Singer John Legend and his fiancée, Chrissy Teigen, have also been vocal about their support of stricter legislation. Other stars like "Parks and Recreation" actor Adam Scott, "Grey's Anatomy's" Jessica Capshaw and Debra Messing, are encouraging everyone on both sides of the debate, regardless of political affiliation, to check out former Rep. Gabrielle Giffords' opinion piece in the New York Times.
