Trump wants a gas tax holiday. There’s a much bigger problem looming - NPR

President Trump has called for a temporary suspension of the federal gasoline tax, which would save drivers up to about 18.4 cents per gallon but would quickly deplete the federal fund that pays for roadbuilding and repairs. Analysts warn the Highway Trust Fund is already strained, so a pause could force cuts to transportation projects or require new funding. The proposal would need congressional approval and faces enforcement challenges to ensure savings reach consumers rather than oil companies; it is being discussed alongside Strategic Petroleum Reserve releases and other short-term measures.
