Trump driven by greed

Liberal Elizabeth Warren attacked Republican Donald Trump on Monday during her first campaign appearance with US Democratic presidential candidate Hillary Clinton, calling him an "insecure money grubber" who is driven by greed and hate.

Warren, a leader of the Democratic Party's progressive wing and a potential vice presidential pick, said Clinton had spent her career fighting for liberal values while Trump, a wealthy real estate developer, was focused on boosting his bottom line.

The US senator from Massachusetts appeared with Clinton before a raucous, enthusiastic crowd in Cincinnati, Ohio, targeting a battleground state in a potential preview of a Clinton-Warren campaign team. She repeatedly accused Trump of looking out for himself instead of for average Americans.

"When Donald Trump says he'll make America great, he means make it even greater for rich guys just like Donald Trump," Warren said, standing shoulder to shoulder with a cheering Clinton.

Warren, who has vigorously attacked Trump in recent weeks, called him "a small, insecure money grubber who fights for no one but himself" and warned: "He will crush you into the dirt to get whatever he wants. That's who he is."

The capacity crowd repeatedly roared its approval, and a line of supporters who could not get inside stretched out the door and down the street. At one point, Warren stopped her speech to turn and applaud Clinton, a former secretary of state.

"She knows what it takes to beat a thin-skinned bully who is driven by greed and hate," said Warren, known for calling for reining in Wall Street and eradicating income inequality.
