Trump trial: Judge rebukes Michael Cohen ahead of expected testimony Monday

"I am very regretful of my youthful indiscretion," Trump White House aide Madeleine Westerhout said, explaining that she left the White House after sharing information with reporters at an off-the-record dinner.

Trump appeared to confer with Blanche as Westerhout began to cry.

Fighting back tears, Westerhout said she has "grown a lot since then."

She spoke through tears and choked up as she told the jury about why she wrote her book about her time in the White House.

"I don't think he was treated fairly and I wanted to tell that story," Westerhout said of Trump.

In June of 2017, Trump White House aide Madeleine Westerhout sent Trump Organization executive assistant Rhona Graff a photo and said then-President Trump wanted it framed.

"President Trump wanted to put in a frame to put behind his desk in the office," Westerhout testified. "Behind the Resolute Desk there was a little credenza."

Graff responded that she had no empty frames and offered to go to Tiffany & Co., next door to the Trump Tower, but she said the frames were "on the pricey side," about $650.

"Does DJT want to spend that much?" Graff asked in the email.

"Is this the type of thing that Mr. Trump would want to weigh in on?" prosecutor Becky Mangold asked Westerhout.

"I don't recall another instance like this," said Westerhout, but she said this was a photo of Trump's mother that he wanted it framed.

"We may have made the executive decision without his approval," Westerhout said. She glanced toward Trump sitting at the defense table, and said, "Sorry, sir."

Jurors saw an example of Donald Trump individually approving an expense. Prosecutors showed the jury a handwritten note on Trump's bill for the Winged Foot Golf Club. The bill totaled approximately $7,000.

"PAY," the note said. "ASAP OK."

"Whose handwriting is that?" prosecutor Becky Mangold asked Trump White House aide Madeleine Westerhout.

"That's the president's," Westerhout said, referring to Trump. "That looks to be a Sharpie or another felt tip pen."

Trump White House aide Madeleine Westerhout testified that Trump would sometimes receive a stack of checks to sign from the Trump Organization that was sometime "maybe half an inch thick."

"It was consistent -- maybe twice a month," she said about the frequency of receiving a package of checks.

Asked about the number of checks in each package, Westerhout said, "Sometimes there was one. Sometimes there was a stack -- maybe half an inch thick. I never counted them."

From the times when Westerhout saw Trump signing checks, she recounted that Trump signed the checks individually using a felt-tip pen.

Once he was done signing, "He would give the folder back to me, and I would put it in a pre-labeled Fedex envelope and send it back to the Trump Organization."

If Trump had a question about any of the checks, Westerhout said Trump would call then-CFO Allen Weisselberg.
