It was pretty common to see on FR back in the day, along with the poorly-typed exclamation points: !!11!1!1. 
I was just about to correct the op for the spelling error.
I have an editor's brain. I can't help it. I hate plural nouns with apostrophes too.
And sentence fragments. 
It's conceivable that there are a treasure trove of recorded phone calls that SC Meuller has in his possession and not just from Cohen's office.
There could be hundreds of recorded tRump phone calls of him saying a lot of awful, bad or illegal things.
Most newer VOIP phone systems have the phone recording feature built in: date, time, WAV file recording. It's all logged, mostly so that callers cannot say they didn't say something over the phone. A legal or Real Estate office or financial institution would be advised to use such phone capabilities. Our VOIP system does that. Would you like to hear what I said a week ago during some random conversation? It's there and I cannot delete it.
The phone recordings are usually stored for some time. Cohen wouldn't necessarily need to do anything or get involved, it would just be something his phone system would do as a normal course of business. And the FBI would know to pull those recordings and phone logs. No question about it!
Imagine the possibilities.
