After having seen how he successfully weasels his way through interviews with what seem to be subject matter experts (I can't really judge but based on context), I don't think he'll have any problems dealing with congress.
Congress are expert weasels though, so they ought at least to be able to call him out for it, though they may be too dumb to understand in what way they're being weaseled.
I never heard of that Coffeezilla guy before the whole FTX debacle, but I got to say I love his penchant for clearly, blatantly, and with no nonsense calling these sort of people out to their face.
