A lot of us speculated that Meghan was freaking out about COVID19 because it affects her now, so she was shaming anyone who was treating it lightly and telling them to stay home. Now that we know she's pregnant, and far enough to know the gender, it makes perfect sense why she was so enthusiastically working herself up whenever the topic came up. She probably wants people to stay at home and be diligent so that her hospital appointments are hassle free.
(She's also being affected regardless, but it makes more sense why she's so passionate about it at the moment)
As for Newt, I recommend listening to season two of Slow Burn. It's all about the Clinton impeachment and how Newt went out of his way to go after Bill. Being partisan usually means going with Republicans while they can do whatever they want. That's what Newt wants more of. The fact that he is against giving nurses more money proves that he doesn't even care about people.
