WASHINGTON (AP) — The White House has withdrawn the nomination of Dr. David Weldon, a former Florida congressman, to lead the Centers for Disease Control and Prevention. The Senate health committee announced Thursday morning that it was canceling a planned hearing on Weldon's nomination because of the withdrawal.

The action in Congress was driven largely by U.S. Rep. Dan Burton, an Indiana Republican whose grandson had autism. Weldon was a prominent voice in Burton’s hearings and co-sponsored a bill that would give responsibility for the nation’s vaccine safety to an independent agency within HHS — an idea that not everyone in public health opposes.
