That was then-Progressive-Democratic Party Presidential candidate Joe Biden’s go-to phrase whenever he wanted to emphasize his seriousness in making a claim.
Here’s one of those serious statements:
If you’re ever working with me and I hear you treat another colleague with disrespect, talk down to someone, I promise I will fire you on the spot. On the spot, no ifs, ands, or buts[.]
When White House Deputy Press Secretary TJ Ducklo was abusive to a Politico reporter, he was suspended for a week without pay and barred from interacting with Politico reporters.
That’s an example of the worthlessness of the now-President’s word as a Biden.
Unless he’s going to stand on the technicality that he didn’t personally hear Ducklo’s abuse, or that Ducklo wasn’t directly working with him at the time of Ducklo’s abuse.
In which case that quibble would be a separate demonstration of the worthlessness of the now-President’s word as a Biden.
In the end, Ducklo was allowed to resign and slink away. Biden, choosing not to fire him, has pretty conclusively shown the worthlessness of his word as a Biden.
