"Trump keeps saying things like, 'You know, uh, I didn't really mean it. It was all part of my reality TV show. Running for president will be on your screen,'" she said at at a campaign rally in Central Falls, Rhode Island on Sunday, impersonating the Republican frontrunner.
"Well, if we buy that, shame on us," she added. "Because he already showed us what he believes, and he has already said what he wants to do, and he wants go after every one of the rights we have."
Earlier this week, Trump's new campaign chief Paul Manafort reassured the Republican National Convention that people should expect a different Trump in the general election. "The negatives will come down. The image is going to change," he said in a private briefing.
"When he's out on the stage, when he's talking about the kinds of things he's talking about on the stump, he's projecting an image that's for that purpose ... you'll start to see more depth of the person, the real person. You’ll see a real different way," he added.
On Sunday, however, Trump himself said he's not "toning it down," and that "everything I say I'm going to do, folks, I'll do."
Meanwhile, Clinton's campaign released a video, called "Extreme Makeover," backing up that claim.
"When someone shows you who they are, believe them," Clinton says at the end of the video, which cuts together clips of Trump's comments on women, immigrants and Muslims, ABC News reported.
