"My view is that Donald Trump needs someone who understands Congress, who can help him work with Congress, who understands foreign policy, domestic policy, economic policy," Dole said Saturday. "You know someone like Newt Gingrich. You know none of us are perfect, but Newt Gingrich is a good fit for Trump, because he can help him in all of those areas and Trump has to listen."
