The White House on Thursday pulled President Donald Trump’s nomination of Dr. David Weldon to lead the Centers for Disease Control and Prevention, multiple sources told ABC News.

The withdrawal came just before Weldon was to appear for his confirmation hearing Thursday morning before the Senate Health, Education, Labor and Pensions (HELP) Committee, where he was expected to be grilled on his past views questioning vaccine safety.
