For those who don't believe grammar is important or that choosing the right word is important (after all, it's only the story that counts), skip this.
I just heard someone on the news say: "But, then, I wouldn't take on the president as a client."
They were talking about the Mueller investigation and how Trump, with his loose mouth, could say something really bad if interviewed under oath. The person I quoted was a former White House (not under Trump) ethics czar. So I was wondering if he was referring to Trump or any president as a client.
I believe the answer is "the" vs "a".
When he said "the president," I believe it's Trump (the current president).
If he had said "a president," I believe it would be any president.
