WASHINGTON — Jose Canseco plans to reiterate his previous support of Roger Clemens when the former slugger testifies before a federal grand jury on June 3.

One of Canseco’s lawyers, Gary Holmes, said yesterday that Canseco’s testimony “will be fully consistent” with a 2008 affidavit submitted in connection with the Clemens investigation.

In the sworn statement, dated March 2008, Canseco wrote: “I have never seen Clemens use, possess, or ask for steroids or human growth hormone.”

The grand jury has been hearing witnesses as it deliberates whether to indict Clemens for allegedly lying to Congress two years ago.
