Manchin's stance on Biden's energy policies causes controversy.

Senator Joe Manchin is supporting a Republican effort to overturn a Biden administration rule that aims to limit pollution from heavy-duty trucks. He cited concerns about the effects on the trucking industry and supply chains, and accused the EPA of creating regulations that will devastate the economy. The rule aims to cut down on emissions of pollutants that can harm the respiratory system and the EPA says it will prevent thousands of premature deaths and cases of childhood asthma annually by 2045. Manchin has also opposed several other Biden administration regulations and expressed frustration with the administration on a range of issues.
