The ad is part of a digital ad buy by the campaign ahead of the primary May 16th.
Unlike in his previous ad for Cosgrove, Sheen is not portraying his West Wing character President Josiah Bartlet, but rather talking about the friendship between himself and Cosgrove.
“I have known Judge Cosgrove for nearly 40 years, not only as a friend and lawyer, but truly as a brother,” Sheen says in the ad.
“Joe and I have worked tirelessly for social justice, for workers’ rights, protection of the environment, and establishment of drug and veterans courts.”
“I ask for your vote on May 16th so the fight for justice can continue,” Cosgrove says at the end of the ad.
Cosgrove is currently a Judge on the Commonwealth Court, he was appointed by Governor Tom Wolf in July.
Cosgrove is running against six other Democratic candidates for two open Commonwealth Court seats. The other Democratic candidates are Rep. Bryan Barbin, Timothy Barry, Irene Clark, Todd Eagen and Judge Ellen Ceisler. The Court currently has six Republicans and one Democrat.
