Trump trial updates: Appeals court denies defense's bid for judge's recusal

Only a few minutes into prosecutor Susan Hoffinger's cross-examination of Michael Cohen's former legal adviser Robert Costello, their exchanges are already sounding tense.

Hoffinger attempted to confirm that Costello boasted about his relationship with Rudy Giuliani, but Costello denied he did so during his first meeting with Cohen.

"You are quoting from an email that is much later," Costello said.

"I am not quoting from an email," Hoffinger replied.

Hoffinger then asked Costello about his relationship with Giuliani.

"He's been to your wedding?" Hoffinger asked.

"Yes he was," Costello said.

“Let’s get the witness please,” Judge Juan Merchan said after taking the bench.

Michael Cohen's one-time legal adviser Robert Costello entered the courtroom and took the witness stand to continue his cross-examination.

“Good Morning, Mr. Costello. Welcome back,” Judge Merchan said.

Former President Trump has arrived in the courtroom.

His son Don Jr., accompanying him to this trial for the first time, is seated in the front row of the gallery.

The prosecution team has entered the courtroom for today's proceedings.
