The New York Times has revealed the FBI interviewed two of Donald Trump’s top White House lawyers earlier this year about classified documents being stored at Trump’s Mar-a-Lago estate in Florida. White House counsel Pat Cipollone and his deputy, Patrick Philbin, are the highest officials known to be interviewed as part of the probe. The Times reports Philbin tried to help the National Archives retrieve the materials but was opposed by Trump, who reportedly said, “It’s not theirs, it’s mine.” Last week the FBI searched Trump’s residence and seized 11 sets of documents. The unsealed search warrant revealed Trump is being investigated for violating the Espionage Act, obstruction of justice and criminal handling of government records.
