This was another case by the conservative law network where the facts were either made up, or so badly misrepresented that they might as well have been made up. This mayor basically walked into the company’s office and said, “I got you those contracts. Give me money if you want any more in the future.”
Not always. Both Trump’s NY fraud conviction, and election interference (hush money) felonies came out of the Michael Cohen hearing, specifically from AOC questions.
Your overall point is absolutely correct, though. It’s even more frustrating when it’s easy to see how powerful these hearings can be.
