Trump Sues California Over Tax Return Law Reuters U.S. President Donald Trump sued California on Tuesday over a new law requiring presidential candidates to release their tax returns to run in the state's primary elections. The lawsuit, filed by Trump's personal lawyers in federal court in Sacramento, argues the statute signed into law last week is unconstitutional because it sets up illegal new rules governing who can seek the presidency. The complaint also alleged that the law retaliates against Trump for his apolitical beliefs and therefore violates his right to free speech under the First Amendment of the U.S. Constitution. The lawsuit follows a similar one filed by Judicial Watch, a Washington-based conservative legal group, on behalf of four voters registered in California - two Republicans, a Democrat and an independent. The Republican Party also filed a similar case on Tuesday. The measure requires presidential candidates to release five years of tax returns in order to appear on a nominating ballot in California, the most populous U.S. state. The bill passed both houses of California's Democrat-controlled legislature and was signed by Democratic Governor Gavin Newsom last week. .
