For their next witness, prosectors have called Rebecca Manochio, a Trump Organization employee.

Manochio, on the stand, said she has worked for the Trump Organization for 11 years, including working as former CFO Allen Weissleberg's assistant for eight years. She now works as a junior bookkeeper at the company.

She said that she is testifying pursuant to a subpoena. "I was compelled to testify," she said.

Manochio testified she was the one who personally mailed the checks for Michael Cohen to Donald Trump in Washington, D.C., while he was president, for him to sign.

"How frequently did you have to FedEx checks to Mr. Trump?" she was asked.

"About once a week," she responded.

"Deb would give me the checks in a manilla folder, and I would put them in a FedEx envelope with a return," she testified.

Manochio said she would send Trump a bundle of checks weekly via Federal Express.

Asked about how many checks she sent at one time, she said, "Maybe between 10 and 20. I am not sure though."

Manochio said she would normally receive the signed checks back within a few days.

"Did you always check to make sure they were signed once you got them back?," she was asked.

"Yes," she affirmed.

"Who's signature was on them?" she was asked.

"Mr. Trump's," she said.

During her redirect examination, Stormy Daniels suggested Trump targeted her in a Truth Social post.

"IF YOU GO AFTER ME, I'M COMING AFTER YOU," Trump wrote in August 2023.

Daniels said that Trump made the post shortly after he sued her for legal fees in Florida.

"I wasn't sure, but I thought it was me," Daniels said about the subject of the post.

Prosecutors previously told Judge Merchan that they planned to introduce social media posts to demonstrate a pressure campaign by Trump against known witnesses in the case.

On recross examination, defense attorney Susan Necheles suggested that the post likely referenced Trump's attitude toward a Republican political action committee, not Daniels' conduct.

With her testimony complete, Daniels stepped off the witness stand and departed the courthouse.

"Have you been telling lies about Mr. Trump or the truth about Mr. Trump?" prosecutor Susan Hoffinger asked Stormy Daniels.

Daniels answered, "The truth," and she said it has cost her.

"I've had to hire security, take extra precautions for my daughter, move my daughter to a safe place to live, move a couple times," she said.

Hoffinger concluded her redirect examination with this question: "On balance, has your publicly telling the truth about your experiences with Mr. Trump been net positive, or net negative?"

"Negative," Daniels answered.

Prosecutors showed the jury disparaging tweets posted about Daniels, including one that said, "Good luck walking down the street after this."

"Are these two tweets examples of some of the tweets that you have received ... in relation to things you have said publicly about Mr. Trump?," Hoffinger asked.

"Yes. These are tame actually," Daniels responded.

Former President Trump, on his way out of the courtroom at the end of the day's proceedings, assailed Judge Juan Merchan for declining to gag upcoming witness Michael Cohen for remarks he's been making about Trump and the case on social media.

"There is no gag order to Michael Cohen. What the judge did was amazing, actually was amazing," Trump said of Merchan telling prosecutors to ask Cohen to stop making comments.

"Everybody can say whatever they want. They can say whatever they want. I'm not allowed to say anything about anybody," Trump said.

Trump also reiterated that his repayments to Cohen for Stormy Daniels' hush payment were properly recorded in his company's ledger. Prosecutors have said the repayments were unlawfully marked as a "legal expense" to conceal their true nature.

"I didn't do the bookkeeping. I didn't even know about it, but a very good bookkeeper marked a legal expense down as a legal expense," Trump said. "They didn't call it construction. They didn't call it building something or concrete or electrical cost. They called it, very simply, a legal expense to a lawyer -- who's a lawyer, not a fixer -- he's a lawyer."

"A legal expense to a lawyer," Trump repeated.
