Hillary Clinton's campaign spokesman said he did not know whether the Clinton Foundation is presently under investigation for allegations of corruption amid reports that the FBI is looking into the charity.

"There's no basis to believe that. I have no knowledge of that," Brian Fallon said Wednesday evening during an appearance on Fox News.

"There's no evidence to that effect," he added, calling reports about the investigation "baseless."

FBI Director James Comey dodged questions last month about whether a reported probe of the Clinton Foundation had concluded with the investigation into Clinton's private emails, which closed on July 6 without yielding criminal charges for anyone involved.

"You can't read anything at all into Director Comey's inability to answer that question," Fallon said.

The Justice Department alum said law enforcement officials are forbidden from addressing questions about potential investigations in a public setting.

Fallon also denied reports from last week that the Internal Revenue Service has opened an inquiry into the Clinton Foundation.

The IRS has indeed referred a congressional request for an investigation to the arm of the tax agency that looks into nonprofit groups. The referral, made public at the outset of the Democratic convention in Philadelphia, raised concerns about the legal status of the Clinton Foundation's tax-exempt designation.

Clinton's campaign spokesman argued House Republicans had "leaked" a letter from the IRS in an attempt to attack the foundation baselessly.

The Clinton Foundation has expanded its activities to include projects around the world, collecting contributions from foreign governments and corporations even while Clinton served as the nation's chief diplomat.

Congressional Republicans, led by Rep. Marsha Blackburn, noted that the well-connected charity never mentioned its intention to operate globally in paperwork filed with the IRS.

Beyond questions over its nonprofit status, the Clinton Foundation has weathered more than a year of criticism over the pattern of favors that flowed from the State Department to its most generous donors.

Fallon said any donors who expected preferential treatment in exchange for a donation or for paying Bill Clinton to give a speech was "completely foolish for thinking so."
