Does anyone here know the Heimlich maneuver?

I was eating a sarnie and reading this article about our new Attorney General's refusal to cooperate with a congressional inquiry into the destruction of the torture water boarding tapes. (La plus ça change, eh?) Everything was going swimmingly until I got to the point where Mukasey indicated that he couldn't possibly submit any materials or information to the House because to do so would make it appear as if the Department of Justice was "subject to political influence." Now I think I'm choking to death.
