WARREN: At the center of Donald Trump’s crimes and chaos is the millionaire donor he made an ambassador. Republicans and Democrats have been rewarding big donors with cushy Ambassadorships like this for years. It’s Washington corruption at its worst. When I’m President that stops. I’m the only candidate running who’s made this promise. I’ll never give ambassadorships to unqualified donors just because they wrote me fat checks. I’m Elizabeth Warren and I approve this message.
