With Pennsylvania’s recount of the GOP senate primary vote just beginning Friday with no winner yet declared, Dr. Mehmet Oz tweeted a video claiming that he is the “presumptive” Republican nominee.

Oz would not be declared the primary winner until the recount determines he received the most votes. Just 910 votes separate Oz from opponent David McCormick.

Pennsylvania counties must be complete the recount by June 7 and report results to the commonwealth by June 8.
