In February 1999, Thurmond introduced legislation barring health messages on wine bottles, the measure intended to reverse what he called "erroneous and irresponsible" action of the Bureau of Alcohol, Tobacco and Firearms. The legislation transferred authority over labeling to the Department of Health and Human Services from the Treasury Department and increased taxes on wine. Thurmond admitted that he did not usually "favor increased taxes" but maintained that "the only way in which we will be able to finance adequate, impartial and trustworthy research into alcohol-induced diseases such as hypertension, breast cancer and birth defects is to generate a new revenue flow that will be used specifically for investigating such killers." On May 26, 1999, the Senate voted on an amendment to a spending bill exonerating Husband E. Kimmel and Walter C. Short of charges of failing to anticipate the attack on Pearl Harbor that led to American involvement in World War II. Thurmond was noted as one of five Senate members to have been a World War II veteran and back the measure and called Kimmel and Short "the last victims" of Pearl Harbor. In August, Thurmond underwent surgery for an enlarged prostate. In September, Thurmond was admitted to the Walter Reed Army Medical Center for tests, his press secretary John DeCrosta saying in a statement that doctors were interested in the source of Thurmond's fatigue and giving him evaluations.
