A conservative activist group called Grassfire Nation published contact information for five of Hollywood's leading industry stars in an email sent to its supporters on Friday.
The email insisted that Bill Maher, Steven Spielberg, J.J. Abrams, Jeffrey Katzenberg and Morgan Freeman are "guilty by association" to a controversial new ad put out by the Pro-Obama superPAC Priorities USA.
The group published phone numbers that connect callers to the talent and management agencies that represent the men.
The subject line of the email read: "Stop the Obama team 'death ad' funded by leftist elites."
"Grassfire Nation is launching this CITIZEN NOTICE calling on leftist elites to cease and desist this despicable ad," the group said on its website. "These notices will be sent directly to Priorities USA as well as Maher, Freeman, Katzenberg, Spielberg and Abrams — because their money funded this deplorable campaign."
Buzzfeed's Michael Hastings reported that the activists listed nine phone numbers for the celebrities after asking supporters to sign a petition.
"We've included the names and contact numbers below," the group wrote. "Demand they use their influence to get this ad pulled with apologies!"
