Kamala Harris said she disagrees "with any criticism of people based on who they vote for," reacting after U.S. President Joe Biden's reference to Donald Trump's supporters and "garbage."

"I will represent all Americans, including those who don't vote for me," the vice president said.

Harris, the Democratic nominee for president, made the comment to reporters as she prepared to campaign in three states. Her words were an attempt to blunt the controversy over Biden's rhetoric with less than a week until the end of the campaign.

The tumult began Tuesday night around the time that Harris was delivering a unifying message in a speech near the White House. Inside the building, Biden was criticizing Trump's recent Madison Square Garden rally, where a comedian described Puerto Rico as an "island of garbage."

"The only garbage I see floating out there is his supporters. His demonization of Latinos is unconscionable, and it's un-American," Biden said in a campaign call organized by the Hispanic advocacy group Voto Latino. "It's totally contrary to everything we've done, everything we've been."

Biden and the White House rushed to explain that the president was talking about the rhetoric on stage, not Trump's supporters themselves. But Republicans seized on Biden's comments, claiming they were an echo of the time when Hillary Clinton, as the Democratic nominee against Trump in 2016, said half of Trump's supporters belong to a "basket of deplorables."

In attacking Biden, and by extension, Harris, Republicans are glossing over Trump's own history of insulting and demonizing rhetoric, such as calling the United States a "garbage can for the world" or describing political opponents as "the enemy within." Trump has also described Harris as a "stupid person" and "lazy as hell," and he's questioned whether she was on drugs.

Trump has also refused demands to apologize for the comment about Puerto Rico at his rally, acknowledging "somebody said some bad things" but "I can't imagine it's a big deal."

Political attack lines have a history of occasionally boomeranging back on people who use them. For example, Ohio Senantor JD Vance, now Trump's running mate, once described Democrats as beholden to "a bunch of childless cat ladies who are miserable at their own lives and the choices that they've made."

Vance's three-year-old comments were resurfaced once he became the vice presidential nominee, energizing Harris supporters who repurposed the label as a point of pride on shirts and bumper stickers — much like Trump's supporters once cheerfully branded themselves as "deplorables."

On Wednesday morning, Harris' running mate, Minnesota Governor Tim Walz, downplayed Biden's comments in television interviews.

He told "CBS Mornings" that Biden "was very clear that he's speaking about the rhetoric we heard," not the supporters themselves.

Walz made a similar comment on ABC's "Good Morning America," where he emphasized that Democrats' inclusive message.

"Let's be very clear, the vice president and I have made it absolutely clear that we want everyone as a part of this," he said. "Donald Trump's divisive rhetoric is what needs to end."
