WASHINGTON (CBSDFW.COM/AP) – Federal agents carrying court-authorized search warrants have seized documents from President Donald Trump’s personal attorney Michael Cohen.

Cohen’s attorney, Stephen Ryan says the search warrants were executed by the office of the U.S. Attorney for Southern District of New York but they are “in part” related to special counsel Robert Mueller’s investigation.

Ryan says agents seized “protected attorney client communications.”

He is not elaborating on the contents. Ryan says the use of the search warrants is “completely inappropriate and unnecessary.”

Cohen is Trump’s longtime personal lawyer.

President Trump calls FBI raid of the offices of his personal attorney Michael Cohen ‘a disgrace’ and calls the investigation by special counsel Mueller into election meddling `an attack on our country.’
