Donald Trump was found guilty on all counts in his New York "hush money" trial after the jury spent two days in deliberation.

The verdict was immediately celebrated by Democrats, despite a lack of compelling evidence that had led some legal observers to predict a hung jury.

One notable issue in the trial was the credibility of the star witness, Trump's former lawyer Michael Cohen. In closing arguments, Trump's lawyers hammered Cohen as the "Greatest Liar of All Time."

Cohen the "greatest liar"

The jury ultimately rejected the argument from Trump's legal team that Cohen was not a credible witness.

The defense brought up Cohen's criminal past, including his history of perjury. Defense lawyer Todd Blanche called Cohen the "human embodiment of reasonable doubt."

“He's literally like an MVP of liars," he said.

The defense also challenged the prosecution's narrative that the "hush money" amounted to "election interference."

“Every campaign in this country is a conspiracy to promote a candidate, a group of people who are working together to help somebody win,” Blanche said.

Those appeals fell on deaf ears, however. The verdict was announced on Thursday afternoon: guilty on all 34 felony counts for "falsifying business records."

Biden pounces

Another key issue in the trial's closing was the jury instructions, which permitted jurors to disagree on how Trump broke the law. Some saw the unusual guidance as alarming, with law professor Jonathan Turley warning the judge had delivered the "coup de grace" in the case.

The Biden campaign released a statement touting the verdict as proof that "no one is above the law" and blasting Trump as a threat to "democracy."

"There is still only one way to keep Donald Trump out of the Oval Office: at the ballot box," campaign spokesman Michael Tyler said. "Convicted felon or not, Trump will be the Republican nominee for president."

Cohen celebrated the verdict as "an important day for accountability and the rule of law."

"While it has been a difficult journey for me and my family, the truth always matters," he added.

Trump, meanwhile, lamented the verdict as a "disgrace" and nothing more than an attempt to tip the scales of the presidential election.

"This was a disgrace, this was a rigged trial by a conflicted judge who was corrupt," he said.

Trump will be sentenced on July 11, days before the Republican convention in Milwaukee. It's unclear whether he will serve time in prison, but the conviction does not bar Trump from serving as president again.
