My head is continuing to spin on a swivel as I watch and listen to the explanations, excuses and walking back of statements regarding Donald Trump, Michael Cohen, Rudy Guiliani and Stormy Daniels.

Here is what is most confusing to me: Does a lawyer who works for his or her client do anything “on the client’s behalf” without telling the client?

I refer to that hush money payment that the lawyer, Michael Cohen, made to Stormy Daniels, the porn star who alleges having a one-night tryst with Donald Trump (Cohen’s client). Trump says he didn’t have sex with Daniels … but Cohen made the payment anyway.

Enter the former New York mayor, Giuliani, who now serves on the president’s legal team.

Trump has denied any knowledge of Cohen’s payment to Daniels to keep her quiet about the (alleged) tumble she took with Trump. Then the ex-mayor says Trump knew about it after all. Giuliani adds that Cohen made the payment without telling Trump precisely why he made it.

Huh? Do I have that essentially correct?

A lawyer worth a damn — and it’s not clear to me that Cohen fits that description — doesn’t shell out a six-figure payment to someone on the client’s behalf without telling him in the moment, if not beforehand. Isn’t that what good lawyers do?

I’m not a lawyer. That’s patently obvious. Another lawyer, though, is certainly paying careful attention to all of this. He’s a good one, too. That would be special counsel Robert Mueller, who has hired a legal team that is poring over all of the bobbing, weaving, dodging and ducking.

Stay alert, Mr. Special Counsel.
