This is why US should never allow blanket pardons or pardons before a conviction.
Not sure if this is really a great example to make your point, considering Maxwell was convicted already, and Trump wouldn't need to issue a blanket pardon to get her out of prison in exchange for her testimony.
The real issue here is that Trump knows there's no consequences if he does pardon her. He wouldn't get removed from office over it, and I doubt the House would even bring articles of impeachment. The Supreme Court has conceded him all the power, and Congress is too spinless to hold him accountable for anything.
Sorry for the Reddit and Twitter links, but this meme is old, at least two years old, and the watermark for the creator of this seems to be from @johnhackerla on Twitter who seems like someone I wouldn't trust with monetary policy.
I'm not sure which day the stock market was like this in 2022-2023 but I assume it was during the period where the Fed was trying to manage a "soft landing" coming out of the Covid pandemic and avoiding a recession.
