The White House claims Vilsack moved on this, not them.
Vilsack is in the cabinet, and thus IS the white house.
No. He is part of the executive branch and works directly for Obama, but he runs his own department so he can take his own initiatives on issues that don't rise to the level of concerning either Obama or Obama's political staff. His office isn't in the West Wing, which is part of the White House. I do not take "the White House" to stand in for the entire Executive Branch, only the President and his West Wing staff.
This doesn't mean that the White House wasn't involved, but they're claiming they weren't.
