“I am here today because I’m with her,” Warren told the crowd as she introduced Clinton. “Hillary fights for us. You know I could do this all day, right?”
While at the lectern, Warren criticized Donald Trump.
“Donald Trump believes in defrauding students to help himself,” Warren said. “He is a thin-skinned bully who is driven by greed and hate.”
