The White House is urging congressional lawmakers to maintain their cool as the war in Iran continues its 12th day. The White House argues that the short-term spike at the pump is needed for a long-term gain. While Republicans in Congress are largely supportive of President Trump's military campaign in Iran, many are anticipating potential fallout and midterm headaches. The cost of the war is unknown as lawmakers have not been estimated at $5.6 billion. The biggest concern is the impact of the conflict on oil prices. Some worry that a protracted conflict with Iran could cause high oil prices to upset voters.
