Nearly 1,500 lawyers from around the U.S. have signed an open letter to the American Bar Association condemning Rudy Giuliani and other Trump campaign lawyers for subverting democracy, saying they could be disbarred for violating their oath to the U.S. Constitution. The lawyers write, “A license to practice law is not a license to lie.”

Giuliani was hospitalized with COVID-19 Sunday after he consistently refused to wear a mask or practice social distancing in multiple public appearances around the U.S. Both chambers of Arizona’s state Legislature and Michigan’s House of Representatives have suspended work following Giuliani’s positive test, after lawmakers came in close contact with Giuliani and his team.
