So Democrats care so much about our green house gas emissions that they want to ban cars and beef but are willing to release metric tons of gas when it politically suites them?
We don't have confirmation that it was the US but careless statements by Joe Biden mean that the US gets the blame. Biden made statements that the US could shut the pipelines down and the the state department warned EU countries about the risk of attacks on the pipelines occurring about now.
US: Those are some nice pipelines that you have there, it would be a shame if something were to happen to them by accident.
