John Dingell: “It is clear to me that Food and Drug needs strong and clear authority over compounding pharmacies, which it now lacks.”

I find it deplorable, disturbing, and downright devastating--to you, to GM, to folks in Michigan who live and breathe pride in our auto industry, but most of all, to the families of the victims.

Now, again, Ms. Barra, it is also important that all automakers communicate clearly and promptly with NHTSA.

A culture that allowed safety problems to fester for years will be hard to change.

I look to her and the GM leadership for establishing more responsible and communicative cultures at GM.
