A former senior CIA official who admitted he made up a phony 'highly classified' government program to help him buy real estate and hundreds of gold bars also gave sensitive US intel to a foreign official.

David J Rush confessed to fabricating the scheme to justify the acquisition of luxury property in south Florida that he intended to resell for personal profit, according to a court filing. 

In a plea document, Rush also admitted he gave away 'certain descriptive information' to a foreign official which could 'endanger the safety and life of the human source and the US government officers working with the source.'

'The disclosure of such information could endanger the safety and life of the human source and the US government officers working with the source and jeopardize the US government's ability to recruit human sources, who rely on the US government's assurance of absolute secrecy,' the document read.

The Department of Justice did not identify which foreign government the official worked for nor did they accuse Rush of profiting off disclosing the information. 

'By his own admission, David Rush defrauded the government of hundreds of millions of dollars, and then misused those funds for extravagant purchases,' added FBI Director Kash Patel. 

'Rush betrayed his oath, his co-workers, and the American people and he will now face justice for his actions.'

Rush separately concocted a bogus 'sensitive government activity' to obtain the gold bars, the filing says.

His fraudulent conduct cost the federal government approximately $194million in total losses, according to the Justice Department.

Prosecutors also accuse Rush of lying to colleagues and government contractors about his military and academic credentials and the fake program that he invented, falsely claiming it was authorized by high-ranking US officials.

'Rush used his legitimate government authority and manufactured personal bona fides to create confidence in his directions,' the court filing says. 

Rush, 49, of Ashburn, Virginia, pleaded guilty to one count of wire fraud, which carries a maximum prison sentence of 20 years, court records show. 

District Judge Michael Nachmanoff is scheduled to sentence Rush on January 28 in Alexandria, Virginia.

'Federal employees are entrusted with serving the American people, not themselves,' Attorney General Todd Blanche said in a statement.

CIA Director John Ratcliffe said the agency immediately referred the matter to the FBI after an internal investigation turned up evidence of Rush's crimes.

'David Rush abused his position and betrayed the public trust and should be held fully accountable for his actions,' Ratcliffe said in a statement.

Several months ago, Rush tried to fraudulently authorize the release of $100million from a government contract, according to Tuesday's filing. 

He directed somebody else to transfer approximately $145million to a holding company formed at his direction, then used those funds to acquire four 'luxury' properties in Palm Beach and Hobe Sound, Florida, the filing says.

In previous court filings, prosecutors said Rush stashed over $40million worth of gold bars from the federal government at his Virginia home. 

They also accused him of fraudulently claiming tens of thousands of dollars in compensation for military leave after he was honorably discharged from the US Navy in 2015.

Rush was arrested after FBI agents raided his home and found more than 300 gold bars worth over $40 million, $2 million in cash and 35 luxury watches - many of them Rolexes.

A judge ordered Rush to be held without bond after his initial court appearance earlier this year.

During a hearing in June, defense attorney Jessica Carmichael said Rush wasn't charged initially with any crimes related to the discovery of the gold bars, which she referred to as 'basically a non-issue' and 'nothing more than a sensational tidbit.' 

She said her client properly obtained the gold bars and kept them locked in a safe in his basement.

'Mr. Rush never claimed they were his,' Carmichael said.

Authorities say Rush lied about his education and military background on job applications, falsely claiming to be a former Navy pilot who graduated with a bachelor's degree from Clemson University in South Carolina and a master´s degree from Rensselaer Polytechnic Institute in New York.

Investigators determined that he didn´t serve as a Navy pilot and didn´t attend either school. 

Rush enlisted in the Navy in 1997 and was honorably discharged from the US Navy Reserves as a lieutenant in 2015, according to the FBI affidavit.
