Livingstone was working nearly anonymously in the White House as director of personnel security until recently, when it was disclosed that an underling, Anthony Marceca, had obtained the personal files of hundreds of Republicans from the FBI.
These files have raised suspicions that Livingstone and Marceca were up to no good and might have been compiling dirt on people the Clinton administration didn t like.
Now that Livingstone is in the spotlight for possible wrongdoing, questions are being raised as to whether he was also part of a damage-control team the night Foster died.
Here s what is raising eyebrows:
In the official report on Foster s death, which was issued by Independent Counsel Robert Fiske in June 1994, it was simply reported that "the keys to [Foster s] car were located in Foster s pants pocket."
That would be fine if it wasn't for the fact that investigators for the Park Police, which investigated the death that night, reported that they couldn't find any keys while Foster s body was still at Fort Marcy Park.
John Rolla, a Park Police investigator and one of the first people at the death scene, was asked in his 1994 deposition given to the Senate Whitewater committee if he found any keys in Foster's pockets while the body was still at the park.
Rolla answered, "I searched his pants pockets. I couldn't find a wallet or nothing in his pants pockets... We searched the car, and we were puzzled why we found no keys to the car."
Rolla said he and Cheryl Braun, another investigator, went to the morgue sometime later - the time is in question - to re-check the body. Rolla and Braun said it was about 8:45 p.m., but the Fiske report says the body didn t arrive at the morgue until later that night.
The White House said it knew of Foster's death at 8:30 that night, but there are reports that Clinton's people knew about the death much earlier.
Rolla said Braun found the keys in Foster's pocket at the morgue, even though he had missed them while the body was still at the park. The keys were found in his right-side pants pocket after the body bag was unzipped.
In her deposition, Braun confirmed that she found the keys after the re-check at the morgue. Braun said she and Rolla had assumed that Rolla had missed checking one of the pockets that contained the keys.
The keys are important, of course, because Foster would have needed them if he did indeed drive himself to the park. If there weren't any keys, then Foster and his car had to have been delivered to the park some other way.
Here s where Livingstone and associate White House counsel William Kennedy come into the picture.
For reasons that are unclear, the two men went to the morgue to identify Foster's body some time that evening. Neither man mentioned what time that was, and it is unclear whether it was before or after Braun had suddenly located the keys at the morgue.
But Hugh Sprunt, an expert on Foster s death who has consulted with Independent Counsel Kenneth Starr, says an employee at the morgue has confirmed he two White House officials visited before Braun suddenly found the keys. This fact was mentioned to Starr by Sprunt, and Starr knows how to contact the employee.
What's curious to people who have studied the case is that Foster's body had already been positively identified, and Livingstone had already told Kennedy that Foster had killed himself. Even Rolla and Braun couldn't figure out why the two White House officials wanted to view the body, but they gave permission anyway.
It was unclear whether someone from the morgue stayed with Livingstone and Kennedy when they viewed the body. One Senate investigator was obviously concerned that something had been planted on Foster's body and asked Rolla if that could happen.
As I've mentioned before, Starr's office had suspicions early on that Foster may have killed himself somewhere else and that the body had been moved to the park.
I know this because I had a conversation with investigators about a possible "safe house" that might have been used by the Clinton administration.
The implication was that Foster might have killed himself at that house. If that had happened, the dead man wouldn't have needed the keys to get himself to the park.
"One of the things I've told Starr's office [is] that I think it is definitely worth determining what the real story is with the keys. It appears to me that Livingstone and Kennedy could have put the keys into Vince Foster's pockets," says Sprunt.
