Former Special Counsel Robert Mueller refused to deny that his team leaked details to CNN regarding an FBI raid on former Trump advisor Roger Stone’s home.

U.S. Rep. Chris Stewart (R-Utah) asked Mueller directly during the former special counsel’s testimony before the House Intelligence Committee whether the office tipped off CNN of the incoming raid on Stone’s Florida residence in February.

“Are you aware of anyone on your team having given advanced knowledge of the raid on Roger Stone’s home to any person or the press including CNN?” Stewart asked.

“I’m not going to speak to that,” Mueller responded.

Mueller’s answer comes amid scrutiny over how CNN, which was the only news organization to stake out Stone’s home for his arrest, knew that there was going to be a raid on the political consultant’s home in Fort Lauderdale.

In April, the FBI refused a records request from The Federalist for emails with CNN on the day of the raid, raising further suspicion that a government official leaked the anticipated raid to the cable news network.

CNN has repeatedly denied that they were given special information in advance of the raid.
