Senate Judiciary Committee Chairman Lindsey Graham said he wants a briefing from the FBI on the tactics it used last week when agents arrested President Donald Trump’s confidant Roger Stone as part of special counsel Robert Mueller’s Russia investigation.

Stone, who was charged with lying about his pursuit of Russian-hacked emails damaging to Democrat Hillary Clinton’s 2016 election bid, was arrested by the FBI in a raid before dawn Friday at his home in Fort Lauderdale. CNN aired video of the raid, which showed agents in body armor brandishing large weapons and night-vision equipment, running up to the home and banging on the door.
