The downgrading of the U.S. credit rating could trickle down to directly affect Massachusetts communities.
Moody's Investor Services has revised its outlook to "negative" for a dozen Massachusetts cities and towns and two regional high schools, saying the governments are "vulnerable" because they depend heavily on federal dollars.
Those communities include Newton, Lexington, Hingham, Wellesley, and Brookline.
Brookline Town Administrator Melvin Kleckner joined Morning Edition Tuesday to discuss the implication of the "negative" rating.
