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

The White House has pulled the nomination of Dave Weldon as CDC director hours before he was set to appear for his confirmation hearing.

Weldon was told Wednesday night that his nomination was being withdrawn, another Trump administration official said.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.
