Senate Majority Leader Bill Frist, R-Tenn., was updated several times about his investments in blind trusts during 2002, the last time two weeks before he publicly denied any knowledge of what was in the accounts, documents show.
The updates included stock transactions involving HCA Inc., the hospital operating company founded by Frist's family.
Frist's sale of HCA stock is under scrutiny by the federal government. Nashville, Tenn.-based HCA said Friday it had received a subpoena from prosecutors for the Southern District of New York, asking for documents the company believes are related to Frist's sale of company stock this past summer.
Prosecutors also have contacted the senator's office, Frist spokesman Bob Stevenson said Friday. He said neither the senator nor his office had received a subpoena.
