Story highlights Hillary Clinton cast Donald Trump's nomination speech as arrogant

"His vision of America is one where we Americans are kind of helpless," she said

(CNN) Hillary Clinton on Friday cast Donald Trump's nomination speech as arrogant and his entire Republican National Convention as dark and depressing, in her first response following the week-long event.

Speaking in Tampa, Florida, Clinton said the Republican nominee "does not speak for anyone" and was not the "voice" that he fashioned himself at the convention in Cleveland. And she took particular offense at Trump's claim that he "alone" could fix the country's problems, characterizing it as self-centered.

"His vision of America is one where we Americans are kind of helpless. We need to be rescued," she said. "I can't really imagine him on a white horse, but that seems to be what he is telling us: 'I alone can fix it.'"

Clinton also poked at the Republican Party's lack of unity, highlighted by a speech in which Texas Sen. Ted Cruz declined to endorse Trump.

"Something has gone terribly wrong when one speaker says vote your conscience and gets booed," Clinton said. "I never thought I would say these words, but Ted Cruz was right."
