Appearing in an ABC News town hall in Philadelphia, Pennslyvania. on Thursday, Oct. 15, Democratic presidential nominee Joe Biden falsely claimed that the Pennsylvania Boilermakers “overwhelmingly” endorsed him.

Biden was asked about his stance on banning fracking. The former vice president has repeatedly said that he would end fossil fuels and fracking but appeared to change course recently. The Biden campaign said his energy and climate platform aims to eliminate new oil-and-gas development on federal lands and waters, but he does not call for a national ban on fracking.

Moderator George Stephanopoulos noted that a member of Boilermakers Local 154, an important union in Pennsylvania, has expressed doubts about Biden’s pledge not to end fracking, saying it was incompatible with his proposal to end fossil fuels.

“The Boilermakers overwhelmingly endorsed me, OK, so the Boilermakers Union has endorsed me because I sat down with them and went into great detail earlier to show their leadership exactly what I would do,” Biden said.

In fact, the Boilermakers Local 154 Union in Pennsylvania, which has 1,500 members, announced last month that they endorsed President Donald Trump’s re-election.

“As the United States continues to lead the world in oil and natural gas production, it is imperative that we continue to battle over-regulations in the fossil fuel industries and fight for American energy production,” they wrote in a statement.

“My members and their families are dependent on these industries, and it is imperative that we continue to develop new opportunities and energy infrastructure in America. Boilermaker jobs specifically rely on coal-fired power generation, and we strongly encourage the advancement of Carbon Capture technologies, which can secure future jobs for our members,” they added.

Natural gas production enabled by fracking is a major industry in Pennsylvania, a critical swing state President Trump carried in 2016. Last month, the president promised to protect blue-collar jobs in a campaign speech in the state.

“They work hard, they do great,” the president said. “We really put them back to work because this state was in real trouble.”
