Congressional hearings are the most useless piece of political theatre that We The People sit through next to the State of the Union Address. They're good for fundraising on the politicians' end and cheap content on our end. As far as having any tangible value to the American people? Meh.
That said, if you're going to engage in the theatre, send the gay Republican! Trump Treasury Secretary Scott Bessent sat before low-IQ octogenarian Maxine Waters, and his performance was fabulous.
