Senator Thomas R. Carper (D-DE) introduced a bill that would replenish the Highway Trust Fund by increasing gas and diesel taxes by four cents a year for four years and subsequently index them to inflation.  The bill would also extend and expand the earned income (EITC) and child (CTC) tax credits by making both credits permanent, as well as expanding the EITC for childless workers and indexing the CTC to inflation.

A press release describing the bill can be found here.
