He’s a bullshitter. It’s from spending all those years in the Senate of accomplishing nothing.
He accomplished making himself and his family a pile of tax-free loot... So there's that.
Note that McConnell and Schumer the other day referenced the horrific immigration/Ukraine billions bill as a product of “the Firm”, meaning the Senate/government combine. I was unaware that there is a “firm” anywhere in the world’s governments other than the British royal family, which really doesn’t govern but calls itself “the firm”. The “firm” in the US is the people, NOT a few legislators who got rich off them and intend to continue to do so, no matter the conseqences to the people they supposedly “represent”.
