CNN has the view from Roger Stone’s arrest in Florida this morning:

A number of law enforcement vehicles with silent sirens flashing pulled in front of Stone’s home on a darkened Ft. Lauderdale street just after 6 a.m. Friday morning.

About a dozen officers with heavy weapons and tactical vests fanned out across Stone’s lawn.

Law enforcement shined a flashlight into Stone’s front door before one officer rapped against it, shouting, “FBI. Open the door.”

Seconds later, the agent shouted, “FBI. Warrant.”

A floor light turned on and moments later, Stone appeared in the front entryway.

“Roger Stone invoked his Fifth Amendment protection as he declined to share documents and testimony with members of the Senate Judiciary Committee,” Politico reports.

“Stone told Politico on Monday that he doesn’t have a pact with Trump’s legal team to share defense strategies, unlike former campaign chairman Paul Manafort, who is in jail after being convicted of tax and bank fraud. But Stone has largely aligned his public messaging on Mueller with the president’s, frequently bashing the special counsel’s tactics.”

Washington Post: “The calls almost always came deep into the night. Caller ID labeled them ‘unknown,’ but Roger Stone said he knew to pick up quickly during those harried months of the 2016 presidential campaign. There would be a good chance that the voice on the other end of the line would belong to his decades-long friend — the restless, insomniac candidate Donald Trump — dialing from a blocked phone number.”

“Those nocturnal chats and other contacts between the man who now occupies the Oval Office and an infamous political trickster have come under intensifying scrutiny as special counsel Robert Mueller’s investigation bores into whether Stone served as a bridge between Trump and WikiLeaks as the group was publishing hacked Democratic emails.”

“Special counsel Robert Mueller’s office is exploring whether longtime Trump adviser Roger Stone tried to intimidate and discredit a witness who is contradicting Mr. Stone’s version of events about his contacts with WikiLeaks,” the Wall Street Journal reports.

“In grand jury sessions and interviews, prosecutors have repeatedly asked about emails, text messages and online posts involving Mr. Stone and his former friend, New York radio personality Randy Credico… Mr. Stone has asserted that Mr. Credico was his backchannel to WikiLeaks, a controversial transparency group, an assertion Mr. Credico denies.”

“Roger Stone claimed on several occasions during the 2016 presidential race that he was in communication with Donald Trump and his campaign, including declaring that he on average spoke with Trump weekly,” CNN reports.

“The nature of that communication is now part of special counsel Robert Mueller’s investigation into Russian interference in the election. Stone is facing scrutiny for his claims to have had a backchannel to WikiLeaks during the campaign. Particularly, investigators are looking into whether Stone shared information that he believed was from WikiLeaks with members of Trump’s presidential campaign,”

“The special counsel investigation into President Trump’s longtime ally Roger Stone is pressing witnesses about Stone’s private interactions with senior campaign officials and whether he had knowledge of politically explosive Democratic emails that were released in October 2016,” the Washington Post reports.

“As part of his investigation into Russia’s interference in the 2016 campaign, special counsel Robert Mueller appears to be intently focused on the question of whether WikiLeaks coordinated its activities with Stone and the campaign, including the group’s timing.”

“On Friday, Mueller’s team questioned Stephen Bannon, Trump’s former chief campaign strategist, about alleged claims Stone made privately about WikiLeaks before the group released emails allegedly hacked by Russian operatives.”

Sources tell ABC News that Roger Stone, a longtime friend of President Trump, “quietly expanded his legal team in recent months, hiring prestigious Florida attorney Bruce Rogow, who will be Stone’s lead attorney on all matters related to the office of the special counsel and all constitutional matters, such as first amendment issues that may arise.”

“Stone’s legal team tells ABC News that last month their client voluntarily took two polygraph tests, which they claim will show Stone passing with flying colors on a spectrum of key issues covering areas of interest in the Mueller probe related o Stone.”

Special Counsel Robert Mueller’s office “has obtained communications suggesting that a right-wing conspiracy theorist might have had advance knowledge that the emails of Hillary Clinton’s campaign chairman had been stolen and handed to WikiLeaks,” NBC News reports.

“Mueller’s team has spent months investigating whether the conspiracy theorist, Jerome Corsi, learned before the public did that WikiLeaks had obtained emails hacked by Russian intelligence officers — and whether he passed information about the stolen emails to Donald Trump associate Roger Stone.”

“Mueller’s investigators have reviewed messages to members of the Trump team in which Stone and Corsi seem to take credit for the release of Democratic emails.”

Meanwhile, Politico reports that Mueller “appears to be locked in a dispute with a mystery grand jury witness resisting giving up information sought in the ongoing probe into alleged Trump campaign collusion with Russia..”
