The White House attempted to walk back President Biden's comments after the president unleashed a firestorm after calling Trump supporters "garbage."

During a virtual Vice President Kamla Harris campaign call with Voto Latino, Biden took a swipe at former President Trump's rally in Madison Square Garden, which made headlines after insult comedian Tony Hinchiffe made jokes mocking different ethnic groups, with one joke referring to Puerto Rico as a "floating island of garbage."

"The only garbage I see floating out there is his supporters," Biden said. "[Trump's] demonization of Latinos is unconscionable, and it is un-American."

His remarks were quickly likened to Hillary Clinton’s labeling of half of Trump supporters as belonging in "a basket of deplorables" in 2016, a comment that was widely seen as undermining her campaign.

White House spokesperson Andrew Bates told Fox News' Jacqui Heinrich that President Biden "referred to the hateful rhetoric at the Madison Square Garden rally as ‘garbage.’"

"The president was referencing a joke by comedian Tony Hinchcliffe in which he likened Puerto Rico to an island of floating ‘garbage’ in the middle of the ocean," he said.

Later, Biden tried to further clarify his comments, saying that he was denouncing Hinchicliffe's comments – not Trump supporters.

"Earlier today I referred to the hateful rhetoric about Puerto Rico spewed by Trump's supporters at his Madison Square Garden rally as garbage—which is the only word I can think of to describe it," Biden wrote in a post on X. "His demonization of Latinos is unconscionable. That's all I meant to say. The comments at that rally don't reflect who we are as a nation."

Speaking at a campaign event with Trump on Tuesday in Allentown, Pennsylvania, Senator Marco Rubio (R-FL) picked up Biden's remark as "breaking news" and told Trump supporters that Biden had marginalized a huge number of everyday Americans as "garbage."

Trump Campaign National Press Secretary Karoline Leavitt said in a statement that Biden and Harris "despise the tens of millions" who support him.

"There's no way to spin it: Joe Biden and Kamala Harris don't just hate President Trump, they despise the tens of millions of Americans who support him," she wrote in a release.

Backlash from the comments came from both sides of the aisle, with Democratic Gov. Josh Shapiro condemning Biden's remarks.

"I’m giving you my fresh reaction to it," he told Fox News Radio Political Analyst Josh Kraushaar on Tuesday. "I would never insult the good people of Pennsylvania or any Americans even if they chose to support a candidate that I didn’t support."
