House Transportation and Infrastructure Committee Chairman James Oberstar (D-Minn.) and Highways and Transit Subcommittee Chairman Peter DeFazio (D-Ore.) sent a letter to governors, state legislators and state transportation officials on May 14 warning them not to rush into public-private partnerships (PPP) that involve highways. The chairmen's letter said that such arrangements may not protect the public interest and that they will work to break up agreements that do not.
