NEW YORK, United States (AFP) — Jurors return Thursday to a second day of deliberations in Donald Trump’s criminal trial, leaving the Republican presidential candidate and the country waiting for a decision that could upend November’s election.

After weeks of testimony from more than 20 witnesses on Trump’s alleged fraud in covering up a politically damaging tryst with a porn star, the spotlight is now on the 12-strong New York jury.

The jurors — their identities kept secret for their own protection amid nationwide political tensions — are working behind closed doors in a separate room.

The only clues to the direction they are taking come through requests for clarifications. They were due to start off Thursday by reexamining testimony from two witnesses and also hear again the judge’s instructions on how to interpret the law.

Trump, 77, is required to stay in the court building while deliberations unfold. 

Although barred by Judge Juan Merchan with a gag order from attacking witnesses, he has taken out his anger daily on the judge and what he claims is a politically motivated trial.

“It’s a disgrace,” he said late Wednesday. “There’s no crime.”

There is no time limit to deliberations but an acquittal or conviction would require unanimity. If just one juror refuses to join the others, the judge would have to declare a mistrial.

Trump is accused of falsifying business records to reimburse a $130,000 payment to silence adult film star Stormy Daniels, when her account of an alleged sexual encounter could have imperiled his ultimately successful 2016 presidential campaign.

Prosecutors say the fraud was motivated by a plot to prevent voters from knowing about his behavior.

If Trump is found guilty, the political repercussions would far outweigh the seriousness of the charges as, barely five months before the 5 November  presidential election, the candidate would also become a convicted criminal.
