Hillary Clinton blasted Donald Trump Thursday in a campaign speech in Reno, Nev., and accused the GOP nominee of building an entire campaign based on fear and bigotry.

"Donald Trump has built his campaign on prejudice and paranoia," she said. "He is taking hate groups mainstream, and helping a radical fringe take over the Republican Party. His disregard for the values that make our country great is profoundly dangerous."

Trump, who Clinton said has a "long history of racial discrimination," also traffics in "dark conspiracy theories" of the sort one would read in a cheap tabloid.

"He is reinforcing harmful stereotypes, and offering a dog whistle to his most hateful supporters as a disturbing preview of what kind of president he'd be," Clinton said.

Trump "should never run our government or command our military," she said to applause.

Her remarks Thursday come on the heels of her calling Trump a racist, and Trump calling her a bigot.

The GOP nominee "is someone who is, you know, very much pedaling bigotry and prejudice and paranoia," she told CNN's Anderson Cooper.

Her remarks came after Trump declared that same evening at a campaign rally in Jackson, Miss., that Clinton was a "bigot."

"Hillary Clinton is a bigot who sees people of color only as votes, not as human beings worthy of a better future!" the Republican nominee said.

Though Trump has referred previously to Clinton's policies as being bigoted against minority voters, Wednesday marks the first time that he has come right out and accused the Democratic nominee herself of being a "bigot."
