Sean Combs trial updates: Juror dismissed, Kanye West makes brief court appearance

Sean Combs' former personal assistant, Jonathan Perez, testified that he saw something he shouldn't have: a video of "Jane" -- a former Combs girlfriend who took the stand under a pseudonym -- having sex with another man.

Perez testified that Combs' videographer first discovered the video on an iPad. Perez testified that he went to Combs and then to chief of staff Kristina Khorram.

"(Khorram) said that in the future I should just bring it to her and she would communicate to Mr. Combs," Perez recalled on the stand. "I gave her the general gist of the video that it was 'Jane' and another man."

Six months later, Perez testified, Khorram brought the video up again because "she had gotten a call from someone outside the company talking about the video in some capacity." The jury heard his conversation with Khorram that she surreptitiously recorded.

"I just need you to tell me step by step and don't leave out a beat," Khorram was heard saying on the recording. "An outside person brought up something."

The conversation did not reveal who had approached the Combs team, but "Jane" testified that a male escort tried to extort Combs and "Jane" by saying he would release a video from a hotel night.

"It is out and I just need to know step by step where you found it," Khorram was heard telling Perez on the recording. "Don't leave out anything please."

Perez was heard telling Khorram on the recording, "I took the iPad, I went to the office, I saw what he was talking about, closed it."

Perez testified that another employee advised him to delete the video, but he didn't feel comfortable doing that.

Kanye West was briefly able to watch his friend Sean "Diddy" Combs' sex trafficking trial from an overflow room.

Arriving in a black Mercedes-Maybach sedan, West entered the public entrance of the Daniel Patrick Moynihan Courthouse earlier this morning. He wore an all-white outfit and black sunglasses.

Like any other member of the public, he had to take off his belt, empty his pockets, and surrender his electronic devices before going through a metal detector.

"He got treated no different than anybody else," a federal marshal who helped Combs through security said.

As he entered the lobby of the federal courthouse, West ignored most of the questions from reporters, including whether he plans to testify in Combs' defense case.

"Are you here in support of Mr. Combs," ABC News asked.

"Yes," he said while nodding.

West was escorted to an elevator and taken to an empty overflow room on the 23rd floor of the courthouse. West and his entourage were alone in the overflow room with four court officers for approximately ten minutes. He sat in the gallery's front row immediately in front of a monitor displaying a feed of the courtroom.

Charlucci Finney, a music producer and longtime friend of Combs, was also in the overflow room. When Eyewitness News reporter Darla Miles entered the room, Charlucci was pointing out elements of the courtroom setup to West, who watched the screen intently. West watched the beginning of the testimony of Jonathan Perez, a former personal assistant of Combs.

West could not enter the main courtroom where the trial is taking place. At one point during West's visit, a member of Combs' legal team showed up in an overflow room on a different floor, frantically looking for West.

After about thirty minutes, West quietly left the courtroom and exited the courthouse. The flurry of reporters and cameramen who tried to capture his exit interrupted the aftermath of a citizen swearing-in ceremony in the courthouse this morning.

About a dozen newly sworn-in citizens were taking photos outside court when West exited, capturing the flurry of action in the background of their photos.

Kanye West arrived at federal court at 11:20 a.m. in the company of one of Sean Combs' sons.

When asked if he was there in support of Combs, Kanye nodded and said yes.

West told ABC News he was there to support Combs during his trial.

Defense attorney Marc Agnifilo asked Homeland Security Investigations Special Agent Andre Lamon, "How many human smuggling and trafficking investigations that you have been part of have you walked out with boxes of Astroglide?"

Lamon replied on the stand that this was the only one.

"Buy AstroGlide in bulk, that's what it looks like to you?" Agnifilo asked. "Sure," Lamon responded on the stand.

The defense made sure on cross-examination that the jury understood that none of the recovered guns were found lying around Sean Combs' Los Angeles mansion.

"Tell the jury where every single one of the guns were?" Agnifilo asked. "Security room," Lamon testified.

Lamon's testimony has concluded. The next witness is Jonathan Perez, a Combs assistant, who is testifying pursuant to an immunity agreement.
