Roger Stone, a former campaign adviser for President Donald Trump, reportedly exchanged messages with a Twitter persona in August 2016 linked to the hack of the Democratic National Committee.
Stone reportedly sent a private direct message to the Twitter account Guccifer 2.0, who describes themselves as a Romanian hacktivist, The Washington Times reported.
"It was so perfunctory, brief and banal I had forgotten it," Stone said on March 10 of his communications with Guccifer 2.0.
Guccifer 2.0 claimed in a blog post on June 15 that it had carried out the attack on the DNC.
Stone wrote an article about the DNC hack on Aug. 5 for Breitbart News, in which he attributed it to Guccifer 2.0, not to Russian hackers. Then he contacted the Twitter profile.
In one message, Stone said he was happy to learn that Twitter had reinstated Guccifer 2.0 after briefly suspending the account.
"[W]ow. thank u for writing back, and thank u for an article about me!" Guccifer 2.0 wrote in response. "[D]o u find anything interesting in the docs i posted?"
U.S. intelligence agencies allege that Guccifer 2.0 had ties to Russia and that it was Russia that carried out the hacking operation on the DNC. They say this was part of Russia's attempt to interfere with the 2016 election.
Investigations to determine the veracity of the reports of Russian interference are on going.
Trump has been asked if he or any of his campaign team were in contact with Russia, to which he responded with, "Nobody that I know of."
"I myself had no contacts or communications with the Russian State, Russian Intelligence or anyone fronting for them or acting as intermediaries for them," the president added.
Stone downplayed the importance of his contact with the Twitter user linked to the DNC hack.
"Even if [Guccifer 2.0] is/was a Russian asset, my brief Aug. 14 correspondence with him on twitter comes AFTER I wrote about his role in the DNC hacks (Aug 5) and after Wikileaks released the DNC material," Stone told the Times. "How does one collaborate on a matter after the fact."
Stone also appeared on Russia Today on March 9, where he supported Trump's allegation that the Barack Obama administration wiretapped his phones during the campaign.
"I believe that [Trump] was under surveillance by the Federal government, by the intelligence agencies, while he was the Republican nominee for president," Stone said, according to the Independent. "This is a scandal bigger than Watergate."
Kevin Lewis, Obama's spokesman, denied the charges.
"A cardinal rule of the Obama administration was that no White House official ever interfered with any independent investigation led by the Department of Justice," Lewis said. "As part of that practice, neither President Obama nor any White House official ever ordered surveillance on any US citizen. Any suggestion otherwise is simply false."
