3. SOUNDBITE (English) Joe Biden, Democratic Presidential Hopeful:
"Yeah, well, look, it's, uh I think you're gonna see from the campaign an acknowledgement of exactly how it happened and what it did. And, you know, I think it's. Look, they made a mistake. They corrected it. They acknowledged it and they let me know about it. And the outfits that some of the language came from are people who support the plan. So, anyway, thank you."
Democratic presidential candidate Joe Biden is acknowledging that his campaign made a mistake when it failed to cite sources of parts of his climate policy plan that faced accusations of plagiarism shortly after it was released.
Biden's campaign was forced to amend the proposal hours after its unveiling Tuesday because a handful of passages did not credit some of the sources in the plan.
During a visit in Boston, Biden on Wednesday said his campaign will likely explain how the mistake occurred.
Still, he stressed that the campaign has already acknowledged and corrected the mistake, and informed him about it.
"And the outfits that some of the language came from are people who support the plan," Biden said in brief comments before walking away with Boston Mayor Martin Walsh.
Biden is particularly sensitive to charges of plagiarism.
His 1988 presidential campaign ended amid controversy over plagiarized passages in his campaign speech and after he admitted plagiarism on a law school paper.
At the time, Biden said the incident at Syracuse University was a matter of him not knowing the proper way to document sources.
