Who is the woman at the center of the viral coffee chugging moment during Tuesday’s impeachment hearing? The woman dramatically drank her beverage as Lt. Col. Alexander Vindman testified. She tilted her head back to take a big gulp before seeming to remember she was on camera. Her name is Emma Dumain and she's a congressional reporter with the news agency McClatchy. She says she grabbed an oatmeal and large coffee on her way to the hearing, where the world saw her chug every last drop.
