President Donald Trump's longtime confidant and former campaign adviser Roger Stone was arrested by the FBI, his lawyer told CNN early Friday. Police raided Stone's house in Fort Lauderdale, Florida.

Stone, who has a net worth of $25 million, was indicted Friday in the special counsel investigation. He has been charged with seven counts, including obstruction of an official proceeding, making false statements and witness tampering.

This is the first public move by special counsel Robert Mueller, who is conducting an investigation into claims of Russia meddling with the 2016 presidential elections and whether the Trump campaign colluded with them.

Stone is expected to appear in court later Friday, the Guardian reported.

According to reports, the indictment does not accuse Stone of coordinating with Russia's interference in the elections. However, it does detail the 66-year-old's conversations about stolen Democratic emails posted by WikiLeaks in the weeks before Democratic opponent Hillary Clinton's defeat.

In 2017, Stone had confessed he had contacts with a self-described Romanian hacker, "Guccifer 2.0," who claimed to have hacked the Democratic National Committee (DNC) a year earlier and stole information and passed it on to WikiLeaks. Stone said he had "completely innocuous" conversations with the hacker, adding that "it was so perfunctory, brief and banal I had forgotten it," the Washington Times reported at the time.

U.S. intelligence authorities said at the time that Russian hackers were linked to the DNC hack and were also involved in rigging the 2016 presidential elections. Authorities also said that they believe Guccifer 2.0 was an online persona adopted by a Russian hacking group.

For months, Stone — who was also involved in political campaigns of prominent Republicans such as Richard Nixon, Ronald Reagan, George H.W. Bush, George W. Bush — said that he was prepared to be charged, but denied any wrongdoing.

Stone was introduced to Trump in 1979 by his then attorney Roy M. Cohn. For many years, Stone lobbied for Trump's casino business. He later served as Trump's advisor during the 2016 presidential campaign, which he left midway in August 2015 amid controversy.

Stone, who is also a writer, has written five books among which “The Man Who Killed Kennedy: The Case Against LBJ” and “The Clintons’ War on Women” gained much controversy. His most recent book “The making of the President 2016” discusses Trump’s presidential campaign.
