The Senate has voted to roll back emissions standards for heavy-duty trucks set by the White House. Conservative West Virginia Democrat Joe Manchin joined Republicans in Wednesday’s 50-49 vote, setting up a veto by President Biden if the Republican-led House also passes the measure. This comes after environmental groups and some Democrats condemned Energy Secretary Jennifer Granholm’s endorsement of the Mountain Valley fracked gas pipeline earlier this week. Arizona Congressmember Raúl Grijalva said in a statement that “fully greenlighting the pipeline will condemn Appalachian communities to generations of pollution and related health and safety issues, while also doing nothing for our ambitious climate goals.”
