Question: Who are celebrities speaking out on the First Amendment?
Those stars and others have joined together to prop up the First Amendment freedoms of speech, the press, religion, assembly and petition. It’s part of a campaign being run  by the First Amendment Center at Vanderbilt University in Nashville. Brad’s print ad  first appeared Sunday in Parade magazine.
The copy reads, in part, “Thanks to the First Amendment, you can be whomever and whatever you want to be.”
Other celebs participating include country group Gloriana, Mary Chapin Carpenter, John Mellencamp and actor Martin Sheen.
