Controversy is raging over Donald Trump’s initial refusal this weekend to disavow the white supremacist David Duke. Trump has since disavowed Duke’s support. Duke was a leader of the KKK and has said his supporters should consider Trump. Trump initially refused to disavow the leader’s support, but has since backtracked. Both Ted Cruz and Marco Rubio making it an issue with Rubio saying, “We cannot be a party who refuses to condemn white supremacists and the Ku Klux Klan."

Here’s how Philip Rucker and Robert Costa report on the race in the Washington Post today,

“The implosion over Donald Trump's candidacy that Republicans had hoped to avoid arrived so virulently this weekend that many party leaders vowed never to back the billionaire and openly questioned whether the GOP could come together this election year. At a moment when Republicans had hoped to begin taking on Hillary Clinton - who is seemingly on her way to wrapping up the Democratic nomination - the GOP has instead become consumed by a crisis over its identity and core values that is almost certain to last through the July party convention, if not the rest of the year.”
