Leaked U.K. diplomatic cables critical of President Trump have led Britain’s ambassador, Sir Kim Darroch, to announce his departure from Washington earlier than expected. But the story is not yet concluded.

According to one current and one former U.S. government official speaking on the condition of anonymity, Darroch repeatedly leaked classified U.S. intelligence information, including highly classified information, to a journalist for a U.S.-based media outlet. The sources are confirmed by the reaction my related inquiries have received from other government officials.
