Hillary Clinton to chair 9/11 probe committee.
Rep. Jerry Nadler, D-NY, will lead the House investigation.
So the issue at hand is about the federal government's response and environmental clean-up efforts and not about the events of Sept 11th attacks. That is definitely important and should be looked at because the air quality was not safe, people got sick and no one was held countable of those decisions.
The environmental clean-up is the subject of this investigation. The House's first hearing about the post-9/11 cleanup will be next Tuesday while the Senate hearing will begin near the end of June.
