Former President Donald Trump's hush-money trial wrapped up earlier this week, with jurors set to return on Monday for instructions.

While Manhattan District Attorney Alvin Bragg maintains that Trump illegally concealed payments to adult film star Stormy Daniels, his star witness has taken more than a few hits. 

Witness says Cohen told him "Trump knew nothing"

Former Trump lawyer Michael Cohen testified that he worked on Trump's behalf to falsify business records to hide Daniels' payoff.

Yet as the Guardian reported, Trump's legal team called on former Cohen adviser Robert Costello, who disputed the witness' assertions.

In one instance, Trump defense attorney Emil Bove told Costello that he wanted to focus his question "very narrowly," before asking what Cohen said of Trump and Daniels.

"Michael Cohen said, numerous times, that President Trump knew nothing about those payments, that he did this on his own … He repeated that numerous times," Costello replied.

"I don't have anything on Donald Trump"

This is not the first time Costello has taken aim at Cohen's credibility, as the Washington Examiner reported that he also did so when testifying on Capitol Hill earlier this month.

A lawyer who once worked for Michael Cohen accused him on Wednesday of perjuring himself while testifying this week during former President Donald Trump’s hush money trial.

"I read Michael Cohen’s testimony from yesterday's trial in New York on the way down on the train, and virtually every statement he made about me is another lie," Costello told lawmakers.

"I swear to God, Bob, I don't have anything on Donald Trump," Costello quoted Cohen as saying. "I don't have anything on Donald Trump."

Costello further maintained that Cohen, who pleaded guilty to perjury in 2019, desperate to avoid being incarcerated, at one point telling him, "I will do whatever the F I have to do. I will never spend one day in jail."

Cohen admitted to stealing from Trump organization

Cohen's credibility may have been further tarnished when the disgraced former attorney admitted to stealing tens of thousands of dollars from the Trump Organization.

When Trump defense team head Todd Blanche asked Cohen if he has since repaid the stolen funds, Cohen responded that he had not.

Cohen said he "was angry" over the reduction in his bonus and regarded the theft as a form of "self-help," stating, "To have my bonus cut by two thirds was very upsetting to say the least."
