As the war in Iran increases U.S. gas prices to nearly $4 per gallon, some lawmakers are pushing for a temporary suspension of the federal gasoline tax. This move is part of a broader effort to control rising energy costs. The president cannot suspend the federal tax on his own and Congress must approve it. Critics argue that this would provide much-needed relief for families and businesses that rely on their cars and trucks. However, industry group warns that the tax suspension could raise the federal deficit and jeopardize the long-term sustainability of investments for highway and public transit programs. States are also considering offering temporary gas tax holidays as a way to provide relief.
