GOP senator 'cannot and will not' support Donald Trump for president

Republican presidential nominee Donald Trump is being heavily criticized for his remarks on a Mexican-American judge presiding over a lawsuit against his defunct Trump University. Republican Sen. Mark Kirk became the latest to come out against Trump, saying via Twitter and to CNN he "cannot and will not" support him. "I find Donald Trump's belief that an American-born judge of Mexican descent is incapable of fairly presiding over his case is not only dead wrong, it is un-American," Kirk said.
