Michelle joined the PSA ‘Demand on Plan’ campaign.
Hollywood actors and entertainers have joined forces for Demand a Plan, a grassroots effort to curb gun violence in the wake of the Sandy Hook Elementary School shootings.
The effort is spearheaded by the Mayors Against Illegal Guns campaign, launched in July after the Aurora, Colo., movie theater shooting. Since then, a petition demanding gun reforms has gathered more than 700,000 signatures.
Among the stars in the 90-second PSA: Beyonce, Jamie Foxx, Gwyneth Paltrow, Michelle Williams, Jon Hamm and Conan O’Brien.
