President Donald Trump and his campaign committee filed suit in federal court Tuesday to block California’s new law requiring presidential candidates to release their tax filings.

The lawsuit is no surprise, as the president’s lawyer, Jay Sekulow, said shortly after Democratic Gov. Gavin Newsom signed the tax legislation into law on July 30 that the measure “will be answered in court.”

“In passing the law, Governor Newsom and the Democrats in the California legislature who voted for it made clear that they were retaliating against President Trump for his political associations and speech,” Bryan Weir, an associate at the Arlington, Virginia, litigation boutique Consovoy McCarthy, wrote in the 15-page complaint filed in the U.S. District Court for California’s Eastern District in Sacramento.
