Trump trial: Cohen faces Trump team grilling over past lies, recollections

"Let's get the witness please," Merchan said, and Michael Cohen entered the courtroom then took his seat at the witness stand.

Cohen carried a water bottle in his hand as he entered and did not look toward Trump when he passed defense counsel table.

Trump turned away from Cohen to his left and whispered to his attorney Emil Bove as Cohen passed. The former president then appeared to crane is neck to the right to get a look at Cohen as he retook the stand.

As Cohen took his place in the witness box, Judge Merchan reminded him that he is still under oath.

After speaking at the bench to Judge Merchan at a private sidebar for approximately 18 minutes, the lawyers returned to their seats.

At the defense table, attorney Todd Blanche leaned in to whisper to Trump.

"I think we are ready to get started," Judge Merchan said.

As the private sidebar continues, Judge Merchan is standing slightly back on the bench with his arms crossed, as Trump attorney Todd Blanche speaks.

At one point, Blanche and prosecutor Joshua Steinglass appeared to laugh.

Trump, seated at the defense table, is leaning back in his chair and his eyes appear to be closed.

"Good morning, Mr. Trump," Judge Juan Merchan said in his usual fashion after taking the bench.

The proceedings immediately began with a private sidebar between the parties and Merchan.
