Rafael Palmeiro has agreed to release information about his failed drug test to Congress, including the results, dates of the tests and other relevant details. The Baltimore Orioles slugger tested positive for the powerful steroid stanozonol, a person with knowledge of the sport's drug-testing program told The Associated Press on condition of anonymity Wednesday. The person did not want to be identified because the sport prohibits disclosure about test results without authorization. Government Reform Committee chairman Tom Davis, a Virginia Republican, and ranking Democrat Henry Waxman of California issued a statement Wednesday saying Palmeiro has "pledged his full cooperation" with their inquiry. "The Government Reform Committee today is requesting from Major League Baseball documents related to Rafael Palmeiro's suspension for a positive steroids test. The Committee is seeking the results of the drug tests, the date of the tests, and other relevant information," the Davis-Waxman statement said. "He has agreed to authorize the release of all relevant documents to the committee, which will help us fully understand the facts of the situation. Once we review the documents, we will determine our next step." In confirming that he would cooperate with the committee, Palmeiro said that if it has any additional questions, "I am ready and willing to answer each and every one of them."
