The FBI and Justice Department prosecutors have recommended bringing criminal charges against former CIA chief David Petraeus, according to the New York Times.
The Justice Department investigation focuses on whether Mr Petraeus gave Paula Broadwell, a woman he admitted having an extramarital affair with, access to his CIA email account and other highly classified information.
Previously, Mr Petraeus has said he did not provide classified information to Ms Broadwell, who was writing his biography at the time of their relationship.
A spokesman for Mr Petraeus, who served as commander of American forces in both Iraq and Afghanistan, said the retired general had no comment.
Officials have recommended felony charges, the newspaper reported.
The recommendations leave the US Attorney General Eric Holder with a decision to make on whether to seek an indictment against Mr Petraeus, who quit his CIA post in 2012 after the extramarital affair became publicly known.
Mr Petraeus has indicated to the Justice Department that he has no interest in a plea deal that would enable him to avoid a trial, the newspaper said.
US Senator John McCain, a leading Republican voice on national security issues and an ally of Mr Petraeus, in December sent a letter to Mr Holder expressing concern about the Justice Department’s handling of the investigation.
“I cannot ignore the broader concerns raised by the fact that this investigation apparently remains unresolved nearly two years later and that the only information that has come to light is through leaks by unnamed sources within the US intelligence community with knowledge of the matter,” Mr McCain wrote.
An FBI spokesman declined to comment on the report and the Justice Department has not not yet responded to a request for comment.
