Clinton also reaffirmed her support for fracking and pipelines and made it clear that her opposition to the Keystone XL pipeline was a calculated political move.

The transcript was included in an email to Clinton campaign chair John Podesta released this week in a trove of documents by the whistleblowing journalism organization WikiLeaks.

“You know from my perspective, this is just one of these issues,” Clinton said of the Keystone XL pipeline at the meeting. “It’s symbolic and it’s not going to go away.”

“They’re all hanging on to it,” she continued. “So you know Bernie Sanders is getting lots of support from the most radical environmentalists because he’s out there every day bashing the Keystone pipeline.”

“You know, I’m not into it for that,” Clinton told the audience. “My view is I want to defend natural gas. I want to defend repairing and building the pipelines we need to fuel our economy. I want to defend fracking under the right circumstances. . . . I want to defend this stuff.”

One of the people who asked Clinton questions at the meeting disparagingly declared that “environmental extremists are the Democrats’ version of the Tea Party.”

At the meeting, Clinton also said she didn’t “particularly care” about the environmental justice activists who opposed her, according to the leaked transcript. “I’m already at odds with the most organized and wildest,” she told the audience at the Sept. 9, 2015, meeting. “They come to my rallies and they yell at me and, you know, all the rest of it. They say, ‘Will you promise never to take any fossil fuels out of the earth ever again?’ No. I won’t promise that. Get a life.”

Clinton continued: “I’m having conversations in these town halls and these meetings I’m having with a lot of people who break into my meetings, they hold up posters, they scream at me, and all the rest of that: ‘Stop extracting fossil fuels, stop extracting on public lands, come out against nuclear, coal’ you name it. They are after everything and I’m just talking through them. And of course they go support somebody else. That’s fine and I don’t particularly care.”

Podesta and the Clinton campaign have not confirmed or denied the authenticity of the emails. Clinton herself has confirmed, however, the authenticity of excerpts of her paid speeches to financial institutions included in a email leaked by WikiLeaks in which she said she “represented” and had “great relations” with Wall Street.

Clinton made the comments to the construction union two weeks before she came out against the Keystone XL pipeline.

Since her April 2015 announcement of her candidacy for the presidency, Clinton had constantly been asked for her view on the pipeline. She avoided answering the question until late September 2015, when it was largely clear that the Obama administration would oppose it. (The Obama administration formally rejected the Keystone XL pipeline in November 2015, after years of protests by environmental justice groups, and the president said building it would have “undercut” U.S. action on climate change.)

By September 2015 Sanders’ enormous grassroots support had posed a serious threat to Clinton’s bid for the presidency. Sanders was running on an environmentalist platform. He staunchly opposed the Keystone XL pipeline and identified climate change as the greatest threat to U.S. national security.
