Former Vice President Joe Biden dipped into election conspiracy territory on Tuesday, arguing that former Vice President Al Gore did not lose the presidential election in 2000.

During a conversation about his nineties-era crime bill, Biden said that it got worse after Gore lost the election.

“I wouldn’t say lost, when a hanging chad sort of did a few things,” he said to voters in Nashua, New Hampshire at a campaign stop.

Biden’s remark continues a history of doubt that Biden has cast on the results of the 2000 election.

In 2013, then-Vice President Biden insisted to Gore during a fundraiser that he had actually won the 2000 election.

“This man was elected president of the United States of America,” Biden said to Gore. “No, no, no. He was elected president of the United States of America. But for the good of the nation, when the bad decision in my view was made, he did the right thing for the nation.”

A widely hailed investigation funded by eight major news organizations in 2001 concluded that Bush would have won despite the Supreme Court ruling in 2001.
