Roger Stone has been indicted by a grand jury on charges brought by special counsel Robert Mueller, who alleges that the longtime Donald Trump associate sought stolen emails from WikiLeaks that could damage Trump's opponents at the direction of "a senior Trump Campaign official."

The indictment‘s wording does not say who on the campaign knew about Stone's quest, but makes clear it was multiple people. This is the first time prosecutors have alleged they know of additional people close to the President who worked with Stone as he sought out WikiLeaks founder Julian Assange.

“After the July 22, 2016, release of stolen (Democratic National Committee) emails by Organization 1, a senior Trump Campaign official was directed to contact STONE about any additional releases and what other damaging information Organization 1 had regarding the Clinton Campaign. STONE thereafter told the Trump Campaign about potential future releases of damaging material by Organization 1,” prosecutors wrote.

Stone was arrested by the FBI Friday morning at his home in Florida, his lawyer tells CNN. He was indicted Thursday by a federal grand jury in the District of Columbia on seven counts, including one count of obstruction of an official proceeding, five counts of false statements, and one count of witness tampering.

The special counsel's office said he will appear before a federal judge in Fort Lauderdale, Florida, at 11 a.m. ET.

Law enforcement raided Stone's house, and CNN witnessed uniformed and armed law enforcement approach his house just after 6 a.m. in Fort Lauderdale.
