The Republican Party began to fracture over its presidential front-runner, Donald Trump, as Nebraska Senator Ben Sasse vowed never to support the billionaire and Mitt Romney said his remarks over the weekend about the Ku Klux Klan were "disqualifying and disgusting."
As he gains in the polls, Trump has gathered endorsements by other prominent Republicans, including New Jersey Governor Chris Christie, former Arizona Governor Jan Brewer, and Alabama Senator Jeff Sessions. But in television interviews Sunday and Monday, Trump declined to immediately repudiate support for his campaign by David Duke, a former KKK leader.
