WASHINGTON — Senate Judiciary Committee Chairman Lindsey Graham said Wednesday that 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, Florida.
