(CNN) - Republican Gov. Bob McDonnell of Virginia sharply tamped down rumors that he may be resigning as part of a plea deal with federal prosecutors.
"I don't know where these things come up. Some of the press accounts have just been completely out of control about rumors, about resignation, so forth," he told CNN affiliate WTVR in an interview that ran Tuesday.
An agitated McDonnell said the scrutiny has been disappointing.
"Thirty-seven years–no one's raised questions about my integrity or my character," he said.
A conservative blog, The Bearing Drift, made the initial report on Saturday, prompting McDonnell's spokesman to denounce the rumor as "false" on Twitter.
McDonnell has been under investigation by the FBI for his relationship with a certain donor who provided multiple gifts, including large financial contributions, to the governor and his family.
The latest allegations, reported by The Washington Post on Wednesday, revealed the donor, Jonnie Williams Sr. had given $70,000 to a corporation owned by McDonnell and his sister, and a separate $50,000 check to McDonnell's wife. Williams owns a dietary supplement company that the McDonnells have promoted in recent years.
The FBI has not made any announcements about the investigation, nor has it given any indication that the governor will be charged.
For his part, McDonnell maintains that the company has not received special state support, such as state benefits, economic development grants, targeted money from the budget, or board appointments.
"They've really–they've received nothing," he said in the WTVR interview.
As for the resignation speculation, the governor–whose term ends at the start of next year–said there have been "a number of irresponsible" press reports and rumors.
"I am thoroughly enjoying and being incredibly productive, I think, with my team as governor of Virginia," he said.
Virginia law prohibits governors from serving consecutive terms, so McDonnell is not running in this year's gubernatorial election.
