Home and office of former CIA Executive Director Kyle "Dusty" Foggo was serched by hte FBI on Friday, accroding to the CIA.

Foggo, who was the spy agency's third-ranking official, is part of a broad law enforcement investigation into allegations of corruption, according to officials familiar with the probe.

"The FBI and CIA's Office of Inspector General this morning executed search warrants for his agency workplace and residence," said CIA spokeswoman Jennifer Millerwise Dyck.

"The agency is cooperating fully with the Department of Justice and the FBI." (Watch how the inquiry is spreading to poker, bribes and prostitutes -- 3:11)

The Associated Press reported that Foggo has been under investigation by the FBI, Internal Revenue Service, Defense Criminal Investigative Service, the CIA's inspector general and the U.S. attorney's office in San Diego, California, according to FBI spokeswoman April Langwell in San Diego. Langwell told the AP that officials -- under a sealed warrant -- searched Foggo's Virginia home and his office at the CIA's Langley, Virginia, campus.

Foggo, who resigned this week from his job overseeing day-to-day CIA operations, is under investigation over his ties to a defense contractor linked to the bribery case against former U.S. Rep. Randy "Duke" Cunningham, R-California.

Cunningham pleaded guilty in November to accepting $2.4 million in bribes. He is serving an eight-year prison sentence.

Intelligence sources said Monday that Foggo had decided to step down after the resignation last week of CIA Director Porter Goss.

Goss announced he was leaving after what intelligence sources described as a power struggle with National Intelligence Director John Negroponte.

Intelligence officials said Foggo's departure would be "pretty standard" because the executive director "tends to follow the CIA director's career trajectory."

Negroponte's chief deputy, Air Force Gen. Michael Hayden, is President Bush's nominee to replace Goss. (Full story)

The investigations stem from Foggo's relationship with defense contractor Brent Wilkes. The two men have reportedly been friends since childhood.

Legal filings in the Cunningham case allege that an unindicted co-conspirator gave the congressman $525,000 in bribes in return for $6 million in government contracts. Officials have identified the unindicted co-conspirator as Wilkes.

The CIA's inspector general is looking at a contract Wilkes had with the CIA, awarded by Foggo, to see if there was anything improper in the deal.

The contract, valued at $2.4 million, was for providing water and household items to CIA agents operating in war zones such as Afghanistan and Iraq.

In addition, federal law enforcement sources said the probe continues into "outstanding issues" in the Cunningham bribery case and that Foggo is part of those issues.

After reports surfaced last week alleging Wilkes provided Cunningham with limousines and prostitutes at two Washington hotels, Foggo said he had attended poker parties thrown by Wilkes there.

In a statement issued by the CIA, Foggo said he never saw anything "untoward" at the games, and he said any allegation to the contrary would be "false, outrageous and irresponsible."
