There's no credible rebuttal. They are private citizens and they did express an opinion rather that assert, that's on the record.
If the GOPERS could cite the Dems for perjury they would have done so. They didn't because as usual they came up with jack shit.
And what's with your childish credulity toward anything republicans say? They've yet to hold a competent hearing and have mostly made fools of themselves.
Thanks President Bidem for getting all of these republicans to forget about being MAGA stupid, and keep the American Economy just moving along.
So many Republicans just love rewarding themselves with unpaid lavish tax cuts, and then when the bill comes do, they want to make the working American taxpayer pay for them.
