Campaign 2016 updates: Hillary Clinton is making the election a referendum on Trump

Hillary Clinton contended Thursday that Donald Trump has spent his entire campaign "offering a dog whistle to his most hateful supporters," citing as evidence the recent endorsement of his candidacy in an official publication of the Ku Klux Klan.

"They said it's about preserving white identity, and they placed their faith and hope in him," she said, noting the endorsement was written under his slogan of "Make America Great Again."

"You have to ask," she added, "do any of us have a place in Trump's America?"

Clinton focused her remarks here on examples of how Trump has discriminated against African Americans. She was introduced by a woman whose application for an apartment in one of Trump's buildings years ago was denied. The incident later became part of a housing discrimination case.

Trump was "someone who always puts himself first, and doesn’t care who gets hurt along the way," Clinton said.

"If he doesn't respect all Americans, how can we trust him to serve all Americans?" Clinton asked.

Clinton also teased her rival for saying just this morning that he had "the greatest temperament," asking: "He knows we can see and hear him, right?" 

When Trump riffed Wednesday about the need to stay on message, Clinton also wondered if the lines were on his Teleprompter at the behest of his wary staff.
