In January of 2024 Biden paused approvals of pending and future applications for Natural Gas export facility projects.
I doubt he did this to hurt Europe. It's more likely the attack was aimed toward US domestic oil production, because limiting the flaring of Natural Gas at the wellhead, and limiting the export of Natural Gas (along with banning gas appliances in places like NYC) would force oil companies to slow oil production to avoid producing more gas than they could capture and market.
Thankfully, more sane heads have prevailed.
