Congressional staff members are reviewing the documents related to Rafael Palmeiro's (search) failed drug test and don't expect to say anything about what they've learned until next week.

The House Government Reform Committee wants to know whether Palmeiro committed perjury when he testified under oath in March that he had never used steroids. With the Baltimore Orioles slugger's permission, Major League Baseball (search) turned over information related to his test last week.

"Government Reform Committee staff continues to review the documents related to Rafael Palmeiro's positive steroid test and will have no further commendocuments for at least a week," panel chairman Tom Davis, R-Va., and ranking Democrat Henry Waxman of California said in a joint statement Tuesday.

Palmeiro was suspended for 10 days by Major League Baseball on Aug. 1. The next day, Palmeiro agreed in a telephone conversation with Davis to let baseball release information requested by the panel.

Davis and Waxman submitted to baseball a list of what they wanted, including the timeline of Palmeiro's case, the substance for which he tested positive, and details about any previous drug tests taken by the player.

When his suspension was announced, Palmeiro said he never knowingly took steroids. He returned from the ban and resumed playing last week.
