Late Saturday evening, former President Donald Trump officially endorsed his old TV pal Dr. Mehmet Oz in the ruckus Republican U.S. Senate primary race in Pennsylvania. In doing so, Trump, while speaking at a rally in North Carolina, ignited fury and ridicule among some of the loudest voices in Trumpworld. At issue among Trump’s most fervent supporters is the belief that Oz, a Turkish-American TV physician who has hobnobbed with Hollywood’s elite and has flip-flopped on the issue of abortion, isn’t a trustworthy “America First” Republican candidate, compared to fellow candidate Dave McCormick, who has ex-Trump administration officials Hope Hicks and Stephen Miller by his side.

Well, this will certainly test Trump’s pull in the GOP.
