Longtime Donald Trump ally Roger Stone said his communications with an alleged Russian hacker may have been obtained through a Foreign Intelligence Surveillance Act warrant, the Associated Press reported Wednesday.

He said if that's the case, then the leak of that information to the website The Smoking Gun is a felony.

"If these were obtained through a FISA warrant, as I believe, and the information was leaked to the Smoking Gun, that would constitute a felony," Stone said.

In a statement to the AP, Stone said he has hired two attorneys to investigate whether he can prompt the government to "either charge me or admit they have no case whatsoever."

Stone admitted earlier this month to using Twitter to communicate with Guccifer 2.0, the hacker allegedly responsible for breaching the Democratic National Committee last year. U.S. officials believe the hacker is tied to the Kremlin.

While Stone acknowledged the contact, he said he was not aware that Guccifer 2.0 was suspected of being tied to Moscow, and denied having any involvement with Russia whatsoever.

"I have no relationship with the Russian state, Russian Intelligence or any other Russians," Stone said, according to the AP.

Under the Foreign Intelligence Surveillance Act the government can obtain a warrant to collect the communications of the people they believe to be foreign agents.

Several other current and former Trump associates have come under fire for possible ties to Moscow. Former National Security Adviser Michael Flynn resigned from his post last month amid revelations that he discussed sanctions with Russian Ambassador Sergey Kislyak before Trump took office.

He recused himself earlier this month from federal investigations into Russian election meddling or Trump’s ties to the Kremlin.

Other Trump aides, including his son-in-law and senior adviser Jared Kushner, are said to have met with Kislyak, as well.

But Stone is the only member of Trump’s’ inner circle so far to acknowledge that he communicated with a hacker.

The contacts between Stone and Guccifer 2.0 were first reported by The Smoking Gun, before Stone admitted to the contacts himself.
