ANNAPOLIS, Md. (AP) — Maryland's first-in-the-nation law taxing digital advertising by Big Tech companies like Facebook and Google is being challenged in federal court as “a punitive assault" on digital advertising and should be struck down, according to a federal lawsuit filed Thursday by leading trade associations.

The lawsuit, filed in U.S. District Court in Baltimore, contends the law "is illegal in myriad ways.” It alleges the law violates the federal Internet Tax Freedom Act, which prohibits discrimination against electronic commerce, as well as other federal laws.
