I’m so 😡. Stephen Colbert highlights Trump’s hypocrisy & CBS fires him. Matthew Dowd calls out Charlie Kirk’s divisiveness & MSNBC fires him. Jimmy Kimmel jokes about Charlie Kirk’s killer & ABC fires him. Brian Kilmeade says the homeless should be killed & Fox does nothing. Glad I moved to Sweden!

THIS IS HUGE! Researchers at the University of Pennsylvania have developed an antiviral chewing gum that may help reduce the spread of viruses. In lab studies, it cut down viral loads of two herpes simplex viruses (HSV-1 and HSV-2) and two influenza A strains (H1N1 and H3N2) by more than 95%. 🧪🧵⬇️
