Portman says Cruz’s defiance of Trump is 'understandable'

Sen. Rob Portman, R-Ohio, said Thursday that it was “understandable” to him that Sen. Ted Cruz, R-Texas, did not endorse Republican presidential nominee Donald Trump during his convention speech. “I thought in a way the reaction to him not explicitly endorsing Donald Trump probably unified the convention floor more than anything else that I’ve seen,” he tells Yahoo News Senior Political Correspondent Jon Ward.
