White House Press Secretary Earnest called the entire Republican Party out by citing concrete examples of their hateful past:
“Now what is also unfortunate is that Mr. Trump isn’t the first Republican politician to countenance these kinds of views in order to win votes. In fact, that is precisely what every Republican presidential candidate is doing when they decline to denounce Mr. Trump’s cynical strategy, because they are looking for those same votes.
Now other Republicans have successfully used this strategy as well. You will recall that one Republican congressman told a reporter that he was David Duke without the baggage. That congressman was elected by a majority of his colleagues in the House of Representatives to the third highest-ranking position in the House. Those same members of Congress blocked immigration reform. Those same members of Congress oppose reauthorization of the Voting Rights Act. Those same members of Congress couldn’t support a simple funding bill because they are eager to defend the confederate flag.
So those are the priorities of today’s Republican Party. And they will continue to be until someone in the Republican Party decides to summon the courage to stand up and change it.”
