The Trump administration has retracted the nomination of Dave Weldon to direct the Centers for Disease Control and Prevention, or CDC.

Weldon was told Wednesday night that his nomination was being withdrawn, another Trump administration official said. The White House decided to pull Weldon’s nomination when it became clear that he would not have the votes to be favorably reported out of committee because of his past controversial comments about vaccines, the official said.

A person familiar with the matter said the White House pulled the nomination because it became clear Weldon did not have the votes for confirmation.
