Sen. Elizabeth Warren blasts GOP presumptive nominee Donald Trump and also endorses Hillary Clinton for president in a speech Thursday, June 9, 2016. Warren is speaking at the National Constitution Society Conference Dinner just hours after President Obama endorsed Clinton.

"We will not allow a small, insecure, thin-skinned wannabe tyrant or his allies in the Senate destroy the rule of law in the United States of America," Warren said.
