Jeff Flake won't primary Donald Trump in 2020
Former Sen. Jeff Flake announced on "CBS This Morning" on Tuesday he will not run for president in 2020 against President Trump.
Details: “I have always said that I do hope that there is a Republican who challenges the president in the primary. I still hope that somebody does, but that somebody won't be me. I will not be a candidate,” Flake said. The former Arizona senator will join CBS News as a contributor in a new series called "Common Ground."
