Today, Rep. James Ranacci (D-OH) introduced the “Bridge to Sustainable Infrastructure Act,” which would index the federal gas and diesel tax to inflation.  Revenue from the tax would be used to fund the Highway Trust Fund, which is expected to run out of funding this summer.  Senators Barbara Boxer (D-CA) and Rand Paul (R-KY) have proposed funding the Highway Trust Fund with revenue from a tax repatriation holiday (under which U.S. companies could repatriate foreign earnings at a tax rate of 6.5%).
