In 1956, the federal motor fuel tax was established, along with a dedicated pool of money for the construction of an interstate highway system. Those gas tax funds go into the "Highway Trust Fund".
Recently, Joe Biden has proposed a "tax holiday" to lower the price of gas. This would necessarily impact a "trust" the government has maintained for over sixty years.
Does the trust fund have the funds needed to cover the shortfall?
Is this simply an election year gimmick by a president whose disapproval ratings have broken all past records?
