Days after the trial began, an appeal's court today denied Trump's request that the trial be delayed. Trump sought a delay because Judge Merchan refused to recuse himself, because he couldn't invoke a presidential immunity defense and because the judge made his team file motions with a delay to allow for redactions.

By Oct. 17, 2016, Keith Davidson emailed Michael Cohen at his Trumporg.com address with the subject line: “PP v. DD: Important.”

In the email presented during the trial, Davidson said, “My client informs me that she intends to cancel the settlement agreement if no funds are received by the close of business today.”

Davidson testified that Cohen gave him a series of excuses about not paying in a phone conversation. "The conversations didn’t leave me with a comfort level” that the settlement would be funded, he said.

Some of the excuses included the Secret Service setting up firewalls in their email system, the computers being “all f----- up,” and Cohen’s inability to reach Trump who Cohen said was in “4 or 5 different states today” and that he was “doing the best” he could.

Eric Trump is looking up at the screen showing the email between Cohen and Davidson about the side letter agreement as Davidson reads from it.

Davidson goes on to testify that Cohen insisted that only he could keep a copy of the side letter agreement, which Davidson acknowledges was highly unusual.

Keith Davidson testified this afternoon that pseudonyms were used in the settlement to identify Stormy Daniels and Trump: Daniels was "Peggy Peterson" and Trump was "David Dennison." He said they used pseudonyms to ensure additional confidentiality, in case the contract was lost, misplaced or stolen.

Davidson said that he came up with the pseudonyms as stand-ins for the parties, and that he knew someone named David Dennison who was on his high school hockey team. “He’s very upset,” Davidson said, noting that his former teammate wasn't pleased about being associated with the agreement.

When asked by prosecutor Joshua Steinglass whose identities were meant to be protected, Davidson replied, "Stormy Daniels and Donald Trump."

Davidson testified that when the deal between Dylan Howard, the former National Enquirer editor-in-chief, and Gina Rodriguez, Stormy Daniels' manager, fell through, Davidson was pressured into negotiating with Cohen.

"The story is no one wanted to talk to Cohen," Davidson testified.

“Gina approached me. She said, ‘Hey, we have this deal and it’s going to be the easiest deal you’ve ever done in your entire life, and it’s already been negotiated. All you need to do is pay for it and talk to that a------,'” referring to Cohen.

Keith Davidson said when he took over negotiating the deal on Stormy Daniels' behalf — working with Michael Cohen after the National Enquirer backed out — that he "needed to pad the deal" by making the total larger.

"We needed to pad the deal. To compensate me now, because I was added to the deal. And Stormy and Gina weren’t going to take a discount for adding me," he testified.

Keith Davidson said that the "Access Hollywood" tape had "tremendous influence" on Stormy Daniels' story.

"I think before, before 'Access Hollywood' tape, there was very little interest from what I understand," he said.

After the tape resurfaced, Davidson said interest in Daniels' story "reached a crescendo."

"Trump is f-----," Davidson said in a text to Dylan Howard.

"Waive the white flag. It’s over people!" Howard said.

Keith Davidson said that Stormy Daniels was a client who had been referred to him by Gina Rodriguez, Daniels' talent manager.

Asked if he spoke to Daniels during various encounters, Davidson said, “I think I had a brief conversation with Stormy and Gina ... but most of my conversations I believe were with Gina.”

He said that he sent a cease-and-desist letter for Daniels. "There was a blog post or a story posted on the website that stated that Stormy Daniels and Donald Trump had some sort of physical romantic interaction," he testified.

Davidson said he spoke to Michael Cohen by phone and "before I could even get my name out, I was just met with a hostile barrage of insults."

"I don’t think he was accusing us of anything, he was just screaming," Davidson said.

According to Davidson, Cohen thought the story was leaked by Daniels and Davidson said he was calling because Daniels didn't want the story published. He said he was successful and had the story taken down.

Davidson testified that as part of his negotiations with ABC News in possibly having it break the story of McDougal’s alleged affair with Trump, ABC News dangled the opportunity for McDougal to appear on a future season of “Dancing With the Stars.”

“It was discussed a lot,” Davidson said of McDougal appearing on a future season of the long-running show. “There was an inference that best efforts would be made that would happen. But it was never guaranteed. Best efforts were discussed.”

Davidson testified that Rhonda Schwartz, a producer for Brian Ross, was calling regularly to try to secure the interview.

Davidson ended discussions with ABC News after signing a catch-and-kill agreement with American Media Inc., the publisher of National Enquirer.

ABC News did not immediately respond to a request for comment.
