On Sunday evenings, my busiest night for TV viewing, I’m happiest when both Showtime’s The Circus and HBO’s Last Week Tonight with John Oliver are present and offering new editions, as is the case tonight. I love learning new insights and perspectives on issues in the headlines, and I also get a bit of emotional release laughing at some of them. The funny thing is, with these two shows, the places you learn, and the places you laugh, aren’t always on the shows you might expect. But both are, for me, mandatory Sunday viewing. Every week seems to bring a new major crisis or intrigue. This week: Former National Security adviser Michael Flynn’s lawyers requested immunity in exchange for his testimony before congressional committees, and there were no immediate takers. Circus will reflect this turn of events one way – and Oliver, I’m confident, will go at it another.
