From his blog:

New United States COVID cases, because of the record-breaking development of the vaccine and its early purchase and distribution by the Trump Administration, has hit its lowest level in more than one year, and falling fast. I want to thank all within the Trump Administration who pushed so hard for a vaccine and got it done in less than nine months when everybody was saying it would take at least 3-5 years, and probably not happen. Without the vaccine the world would be a much different place right now. Thank you also to the U.S. Military for its incredible distribution and logistical planning. Operation Warp Speed and our decision to purchase billions of dollars of vaccine before it was even approved, has been “One of the greatest miracles of the ages,” according to many. Thank you!
