The Pittsburgh Tribune Review reports that the city council on Monday voted 7-2 to impose the tax. The city says the tax could generate up to $4 million annually.
But a lawyer for Lamar Advertising of Baton Rouge, La., says billboards are protected under the First Amendment. Jonathan Kamin says Lamar will sue in federal court if the bill gets final approval next week.
Last month Lamar used area billboards to criticize council members who proposed the tax.
