I don’t know. A brief internet search reveals the following from CNN in 2022:
“What is Nord Stream 2 and can Biden kill it?”

From the article:
“If Russia invades … there will no longer [be] a Nord Stream 2,” Biden said during a joint press conference with Scholz. “We will bring an end to it,” added the American president.
The right way to combat Russian energy influence was pursued by President Trump. Increase US energy production and exports. That is not what Biden chose to do.
Biden happily lifted Trump’s sanctions on Nordstream2. Democrats prefer Russia supply Europe with energy because that reduces demand for production increases in US oil and gas.
