is a request to NASA for un-redacted information about the SpaceX failures. They're not asking for an investigation or delays (as far as I can tell), they just want disclosure. How is making failure information public going to slow down progress?
In particular, this is probably an attempt to force NASA into selecting Boeing's CST-100 as the agency's new orbital vehicle. Boeing's option certainly has fewer operational "anomalies" than SpaceX's Dragon, because it hasn't even made it to orbit yet -- but don't expect politically-motivated Congressmen to admit that Boeing is a higher risk than a proven, if upstart, solution.
You can't ask "what's wrong with this request" anymore. You have to ask "why would they be asking for this? What do they get out of this information?"
However, I think criticizing their decisions while everyone is still in the information gathering stages is taking vigilance way too far. Politicians are people too and you have to give them a fair shake at doing their job before you can lament the result.
byerley is right though -- I don't see anything asking for an investigation or some other show-stopper.
