The White House has responded to Donald Trump’s failure to correct a supporter who claimed that President Obama is a Muslim and “not even an American” at one of his rallies. The White House made a nuanced point that neither Trump’s reaction nor the supporters words were surprising. In fact, they are endemic of the Republican party as a whole.

White House Press Secretary Josh Earnest said:

People who hold these offensive views are part of Mr. Trump’s base. Mr. Trump himself would be the first to tell you that he’s got the biggest base of any Republican politician these days.
