Arizona Republican Congresswoman Martha McSally called on the national GOP to "grow a pair of ovaries" as she launched her bid for the U.S. Senate on Friday, joining the race to replace retiring GOP Sen.

The governor dodged multiple questions about what he thought of the speeches by John McCain and Jeff Flake, the state's two senators, chiding the president for creating a toxic political atmosphere. Both said Trump was more interested in finding scapegoats than solving problems.
