Over the course of Jeffrey McConney's testimony, the former Trump Organization controller has repeatedly invoked the name of his longtime boss, Allen Weisselberg, when describing the conduct and the paper trail underpinning prosecutors' theory of the case.

He and Weisselberg ate lunch every day, McConney testified, and their offices sat beside each other in Trump Tower. At one point during his testimony, McConney said he recognized Weisselberg's penmanship on a key exhibit because "I've read his handwriting for about 35 years."

But as McConney testifies, Weisselberg sits in jail -- one month into a five-month sentence after pleading guilty to two felony counts of perjury for lying under oath during his testimony in former President Trump's civil fraud trial and during the investigation that preceded it.

Weisselberg is not expected to testify at this trial.

Jurors saw the tax forms that the Trump Organization submitted to the Internal Revenue Service related to Michael Cohen's reimbursement.

Jurors saw two 1099 forms -- one for the $105,000 from Trump's trust and another for the $315,000 paid from Trump's personal account.

Former Trump Organization controller Jeff McConney testified that that the company doubled Michael Cohen's repayment to compensate for the expected taxes he would owe on the payments.

Following the mid-morning break, former Trump Organization controller Jeffrey McConney's testimony resumed and jurors were shown a spreadsheet called -- a query voucher -- that documents the 12 $35,000 payments made to Michael Cohen in 2017.

According to the exhibit, three of the payments came from Donald Trump's trust account, totaling $105,000.

The remaining nine payments were made through Donald Trump's personal account, totaling $315,000.

In a dry, repetitive manner, jurors were shown the invoices that Michael Cohen sent to the Trump Organization to request payment for legal services pursuant to a retainer agreement, in order to repay the hush payment to Stormy Daniels.

The 11 invoices comprise 11 of the 34 criminal counts Trump faces.

Former Trump Organization controller Jeff McConney paged through exhibits showing emails and invoices for each month over the course of the repayment schedule.

Each of Cohen's 11 invoices read, "Pursuant to the retainer agreement, kindly remit payment for services rendered for the month of [name of month]."

McConney testified that he forwarded the invoices to Deborah Tarasoff, who worked in the Trump Organization's accounting department.

"Please pay from the Trust. Post to legal expenses," McConney wrote on February 14, 2017.

Former President Trump, on his way out of court, slammed the proceedings as "a disaster for the DA."

"This was a very big day, a very revealing day," Trump told reporters. "As you see, their case is totally falling apart."

"They have nothing on the books and records and even something that should bear very little relationship to the case," he said.

"It is just a disaster for the DA," said the former president.
