The hacker who goes by the moniker Guccifer 2.0 posted online Tuesday claims he had hacked into the Clinton Foundation's computer system, finding the names of donors and more.

The biggest potential bombshell was the claim some banks that had received federal funds under the Troubled Asset Relief Program (TARP) gave some of the money to Democrats in Congress, including former House Speaker Nancy Pelosi.

Other names included former Massachusetts Rep. Barney Frank, Maryland Rep. Chris Van Hollen, South Carolina Rep. James Clyburn and Illinois Rep. Luis Gutierrez.

One observer on Twitter also noted one folder is labeled "Pay to Play."

"Hillary Clinton and her staff don't even bother about the information security," Guccifer 2.0 wrote. "It was just a matter of time to gain access to the Clinton Foundation server."

The Clinton Foundation denied the files posted are from the organization, and Politico reported experts said they looked more like files hacked from the Democratic National Committee.

"Once again, we still have no evidence Clinton Foundation systems were breached and have not been notified by law enforcement of an issue," an official with the foundation told Politico. "None of these folders or files shown are from the Clinton Foundation."

Others online warned they are fakes.

The hacker is believed by many to be affiliated with the Russian government and is attempting to influence the U.S. presidential election. Russian President Vladimir Putin has said his government has no connection to the hacker.

Guccifer 2.0 said he is looking for a better format to release more of the documents.
