Google has now stopped working with Market Street Partners, which offers "investor relations and financial media consulting for private and public technology companies" according to its website.

Khan, who herself made $500,000 on the Google tip, is now cooperating with federal prosecutors as a witness against the Galleon Group. She reportedly previously worked at Intel, another company reportedly targeted by the insider-trading ring.
And get this: She was sued in 2008 by a maid for alleged violations of labor laws.
