President Trump Michael Cohen Robert Mueller

The FBI executed a no-knock warrant on the office of President Donald Trump’s longtime personal lawyer Michael Cohen on the orders of the U.S. Attorney’s office of the Southern District of New York. During the raid on Monday federal agents seized documents, including tax forms and privileged attorney, client communication, according to Cohen’s attorney attorney Stephen Ryan.

“The decision by the US attorney’s office in New York to conduct their investigation using search warrants is completely inappropriate and unnecessary,” Ryan said.

“It resulted in the unnecessary seizure of protected attorney-client communications between a lawyer and his clients.”

The raid is related to a $130,000 payment made by Cohen to porn star Stormy Daniels to buy her silence prior to the 2016 election. Daniels has claimed she had sex with Trump 12 years ago.

Trump stated he knew nothing about the $130,000 payment made to Daniels.

An earlier version of this post was corrected to show that special prosecutor Robert Mueller did not order the raid.
