Hillary Clinton’s team said Donald Trump was “disgraceful” for accusing the Democratic nominee of being the first to question whether President Obama was really born in the United States.

“Trump’s actions today were disgraceful. After five years of pushing a racist conspiracy theory into the mainstream, it was appalling to watch Trump appoint himself the judge of whether the President of the United States is American,” Hillary for America campaign manager Robby Mook said in a statement.
