Sen. Elizabeth Warren, D-Mass., endorsed Rep. John F. Tierney's re-election bid at a campaign rally in the Bay State's 6th District Monday, calling the House Democrat a "tireless champion for Massachusetts families." “I had the chance to work closely with Congressman Tierney on consumer protection issues years before I ran for the Senate, and I’m very glad to work as his partner in Congress today," Warren said in a release. "Throughout his career, he has fought hard to strengthen our schools, to improve access to high-quality, affordable education, and to make the kinds of investments that grow our economy in the 6th District and across the Commonwealth."
Tierney faces a primary in September against veteran Seth Moulton and attorney Marisa DeFranco. Moulton has raised more money than Tierney — one of only a few challengers to bring in more bucks than an incumbent this cycle — although the congressman has more cash in the bank.
