Senator J.D. Vance, an Ohio Republican, appeared in court on Monday as a key witness for the prosecution in the trial of Michael D. Cohen, former fixer for Donald J. Trump. Mr. Vance, along with other Trump supporters, criticized Mr. Cohen and other trial participants on social media and at a news conference. The judge has prohibited Mr. Trump from making similar attacks.
In a statement to reporters outside the courthouse, Mr. Vance accused everyone involved in the prosecution of being Democratic political operatives, expressing his frustration that Mr. Trump was unable to speak out himself due to the restrictions imposed by the judge.
Mr. Vance’s presence at the trial could indicate a new phase in Mr. Trump’s exploration of potential running mates, as he has been evaluating vice-presidential candidates by their media appearances and campaign involvement.
Despite his previous criticisms of Mr. Trump, Mr. Vance has since become one of the former president’s most outspoken supporters in the Senate. His attendance at the trial on Monday highlighted his loyalty to Mr. Trump.
Throughout the trial, Mr. Trump has been accompanied by aides and allies who provide him with support during the challenging proceedings that have brought to light personal details.
Other Republicans present in support of Mr. Trump at the trial included Senator Tommy Tuberville, Representative Nicole Malliotakis, Attorney General Steve Marshall, and Attorney General Brenna Bird.
Ms. Malliotakis criticized the prosecutor, Mr. Bragg, for focusing on this case instead of other criminal activities in the city.
The district attorney’s office declined to comment on the criticism, citing crime rate statistics showing a decrease in major crimes in the city.
The Republicans present at the trial expressed their dismay at the proceedings, calling it a travesty and a perversion of the criminal justice system.
Mr. Vance dismissed Mr. Cohen’s testimony as unreliable and hoped it would not sway the jurors. The support group inside the courtroom provided live updates on social media to contribute to the trial’s atmosphere.
Among the Republican figures present was Eric Trump, who criticized Mr. Cohen’s testimony as rehearsed. Andrew Giuliani, another Trump ally, also denounced Mr. Cohen as a liar and criticized the Manhattan district attorney’s office for bringing the case.
