(CNN) On the day of his indictment by special counsel Robert Mueller, former Donald Trump adviser Roger Stone seems to have lost the support of one of his greatest heroes, former President Richard Nixon -- or at least Nixon's foundation.

The Nixon Foundation sought to distance itself Friday from Stone after the political provocateur emerged from a Florida federal courthouse flashing the signature double V hand signal, usually used to symbolize "victory" or "peace," that Nixon made when he departed the White House after his resignation. Stone, who has a tattoo of the former president on his back , has long cited Nixon as a key political icon and influence.

"This morning's widely-circulated characterization of Roger Stone as a Nixon campaign aide or adviser is a gross misstatement. Mr. Stone was 16 years old during the Nixon presidential campaign of 1968 and 20 years old during the reelection campaign of 1972," the Nixon Foundation tweeted

The foundation added , "Mr. Stone, during his time as a student at George Washington University, was a junior scheduler on the Nixon reelection committee. Mr. Stone was not a campaign aide or adviser. Nowhere in the Presidential Daily Diaries from 1972 to 1974 does the name 'Roger Stone' appear."

The FBI arrested Stone early Friday morning after he was indicted by a grand jury on charges brought by Mueller, who alleges that the longtime Trump associate sought stolen emails from WikiLeaks that could damage Trump's opponents while in coordination with senior Trump campaign officials. The indictment indicates that several unnamed Trump advisers knew of Stone's attempts.
