This is On Trial, a special series from Dateline True Crime Weekly, bringing you daily coverage from the Sean Combs racketeering trial. He has pleaded not guilty to all the charges against him. I'm Andrea Canning, and it's Monday, June 16th. Just a heads up, in this episode, we're going to be talking about some graphic details and harrowing subject matter.

The government began the sixth week of trial by giving the jury a look at material they pulled off Christina Corum's phone.

We've talked about Christina before. She worked for Sean Combs in various positions over the years, eventually becoming his chief of staff.

And according to prosecutors, her phone contains group chats, audio files, and voicemails that

prove their charge of RICO conspiracy. NBC news correspondent Chloe Malas was in the courtroom

as the prosecution went through all these messages, and she has stepped out to tell us all

about it. Hey, Chloe. Hey, Andrea. Chloe, how was the prosecution presenting this evidence to the jury?

Who was on the witness stand? The woman who testified today, she's a paralegal for the U.S.

Attorney's Office. She's considered something called a summary witness

and basically there to explain how things work and tie up loose ends before this case is over.

She reviewed a bunch of data that had been extracted from different devices, put it into

a 30-plus page roadmap for the jurors saying, here are text messages or even audio messages

when they were sent to whom, from whom, and where you can find it in exhibits later.

So who is Christina, also known as KK., communicating with in these messages?

Everybody from Cassie Ventura to Jane to other assistants.

There's even an exchange about the Cowboys for Angels company that we talked about.

Right. I mean, this is so fascinating.

It's Ryan Lopez, who is one of Combs' former assistants.

Riding to KK, I think I saw one of the cowboys today.

You can spot them in the lobby like an escort.

KK.K. responds with four laughing emojis.

And according to the prosecutor, the messages appeared to show talk of moving drugs around
