When and why did democrats begin supporting fracking?

I was shocked in the presidential debate that Harris gave staunch support for fracking. I was under the impression that democrats are against fracking, and remember people being critical of Fetterman for supporting it.

I also grew up in an area that was heavily impacted by the pollution from fracking. People who worked in the field were seen as failures of moral character who chose profits over the health of their children. How is it that both major parties are now in support of it? I feel like I must be missing a piece of the puzzle.
