LOWELL — Calling Donald Trump a "small, insecure moneygrubber," U.S. Sen. Elizabeth Warren on Saturday unleashed her latest blistering attack against the Republican presidential candidate as hundreds of Bay State Democrats gathered for their convention still divided over who will lead their own party into November.
Warren, who has escalated her attacks on Twitter and in recent speeches against the presumptive GOP nominee, has nevertheless remained on the sidelines in the Democratic contest that will drag on at least through next Tuesday.
