President Donald Trump’s tax returns show no “income of any type from Russian sources,” according to a report Friday from the Associated Press based on a letter from a Trump lawyer. The brief AP report didn’t immediately identify the lawyer. The report punctuates a dramatic week for the president, highlighted by his stunning dismissal of Federal Bureau of Investigation Director James Comey late Tuesday. The Comey firing came as the FBI director was investigating potential ties between Russia and members of Trump’s campaign for the U.S. presidency. Trump has declined to release his taxes to the public, which other candidates for U.S. president have traditionally done.
