The Port of Los Angeles efforts to amend federal interstate trucking laws may be gaining traction – at least among Democratic members of Congress. So far 52 Congress members have signed the “Clean Trucks Legislation” to the House Committee on Transportation & Infrastructure that calls for amending the Federal Aviation Administration Authorization Act, which governs interstate commerce. Of the 52 signers – all Democrats – 37 are from California, New York and New Jersey. Only two representatives from Washington State signed the letter and none from Oregon.
