NEW YORK -- Paul McCartney is adding his voice to Tony Bennett's campaign against gun violence.
The former Beatle recorded a voice message that's part of a text-to-call operation Wednesday for Bennett's Voices Against Violence campaign. McCartney and others are encouraging Americans to send a text, which will lead to the singer's message and connect the caller to their local Senate office after providing their ZIP code.
The Senate will vote Wednesday on a proposal to expand background checks, the linchpin of the effort to curb gun violence. In December, 20 children and six aides were shot and killed at a Newtown, Conn., elementary school, propelling gun violence into a national issue. Families of the Newtown victims have been lobbying lawmakers.
Other celebrities supporting include Alec Baldwin, Gloria Estefan, Josh Groban and Juanes.
