A former New York Yankees baseball player will meet with congressional investigators behind closed doors today.
Four-time all-star Chuck Knoblauch will talk to a house panel that's investigating drug use in baseball.
Knoblauch played with Roger Clemens on the Yankees and is among among five witnesses, including Clemens and pitcher Andy Pettitte, who are scheduled to testify before the panel. Knoblauch retired six years ago.
In the Mitchell report on substance abuse in baseball, trainer Brian McNamee says he gave Human Growth Hormone to Knoblauch and Pettitte and HGH and steroids to Clemens.
Pettitte, Clemens and McNamee are scheduled to give their depositions next week.
