(AP) – Trump answered yes when asked if he would suspend the federal gas tax amid higher prices stemming from the war with Iran.

He said the price of oil and gas would drop “like a rock” as soon as hostilities are over. Asked how long the suspension would last, he said “until it’s appropriate.”

The federal gas tax is 18.4 cents per gallon of gasoline and 24.4 cents per gallon of diesel, according to the U.S. Energy Information Administration.
