It's true that CZ was seeking Trump's pardon ever since Trump got chosen as new US president, but it's not related to that fake USD1 allegation from Bloomberg. As far as i know CZ is confirming that is fake news, and willing to take legal action against Bloomberg.
What should we believe? You don't expect CZ to own up that he has anything related to the USD1 stablecoin, it'll be roping himself into deeper trouble. I know for sure that big business executives makes compromising deals underground all the time and as far as it stays in the coolers they're the good guys. We'll just wait and see how the drama will unfold, it should be interesting to see how the lawsuit will go and if it'll unearth more dirts than what we already suspect. I don't know about the integrity level of CZ but I'm guessing that someone in his position will do everything in his power to regain his glory of once more being the CEO of Binance.
