So basically if anyone doesn’t understand where Tegan and Sara are- they are at the “Not White House Correspondents Dinner” which is a mock event of the White House Correspondents Dinner which is an annual event where members of Congress and the President are publicly made fun of/ roasted in good fun. But Donald Trump is a paranoid asshole and announced he would not be attending the actual White House Correspondents Dinner this year which is a presidential tradition. So Samantha Bee, being petty, created the NWHC dinner to toast trump anyway. Which is amazing just in that sense and the fact that Tegan and Sara were invited is even more beautiful and amazing.
