Watching Powell's testimony before Senate committee, which is never about a good faith questioning rather than producing soundbites and whatnot. Congress critters wouldn't say much different if there were zero question marks at the end of their statements.
Essentially, Tim Scott is using this as one more opportunity to run for Vice President indirectly.
I'm no fan of Scott and there's plenty I disagree with him on, but he's not... at a cringe-worthy level of embarrassment for the country. That's more than could be said for Biden, Trump, or Kamala... so he's got that going for him.
