Samantha Bee weighed in on the Democratic upset in a special election in Pennsylvania:

“Just two years ago, Trump won this district by 20 points. Two years before that, Democrats didn’t even bother running an opponent against the Republican incumbent. You know, I’m really enjoying this radical new Democratic strategy called ‘trying.’”
— Samantha Bee

“Hey Democrats, you know that delectable, unfamiliar aroma you’re smelling today? It’s blood in the water. And yes, I know you’re vegans, it’s fine — it’s hummus in the water. Just get to work.”
— Samantha Bee

“It is spring break. Spring break is that special time of year when memories are made — and then completely forgotten by tomorrow morning.”
— Jimmy Fallon

“In addition to Rex Tillerson, Gary Cohn and Hope Hicks, we also learned that Trump’s personal assistant was just fired — although he was actually escorted from the White House on Monday. I assume he wanted to beat the rush.”
— Stephen Colbert
