RORY: Okay, I have something to tell you.
LORELAI: Is it about Vince Foster?
Vincent “Vince” Foster (1945-1993), attorney who served as deputy White House counsel during the first six months of the Clinton administration. A childhood friend of Bill Clinton, he was unhappy working in politics, and became severely depressed. He was found dead from a gunshot wound in Fort Marcy Park in Virginia, just outside Washington DC, with a torn up resignation letter in his briefcase. His death was ruled a suicide, but several tabloids and newsletters speculated that he had been murdered, possibly involving the Clintons themselves.
Lorelai jokingly questions Rory, as if she is expecting her to provide inside information on the case (because Rory is in student government now).
