Hunter Biden, son of US President Joe Biden is currently facing a federal criminal trial.

During a brief recess in Hunter Biden’s trial on federal gun charges, his wife, Melissa Cohen Biden, confronted Garrett Ziegler, a former Trump White House aide.

The confrontation took place in the hallway of the J Caleb Boggs Federal Building on Tuesday. Upon seeing Ziegler, Melissa Cohen allegedly approached him, pointed her finger in his face, and loudly accused him, saying, “You have no right to be here, you Nazi piece of s****.” Ziegler did not respond to the confrontation, and Cohen then walked away.

In response to the incident, Ziegler told NBC News, “It’s sad I’ve been sitting here the whole time and haven’t approached anyone.” He further clarified, “For the record, I’m not a Nazi, I’m a believer in the U.S. Constitution. I haven’t said one thing to them.”

Ziegler, who worked in the White House under Trump adviser Peter Navarro, is known for his vocal criticism of Hunter Biden.

Post-White House, he has focused on scrutinizing Biden’s financial records and personal life, publishing allegedly incriminating or embarrassing details through his nonprofit website, Marco Polo. He admitted to being “obsessed” with “studying the [Biden] family” in an interview with The Washington Post.

His website played a central role in circulating embarrassing photos, videos, emails, and more from Biden’s laptop. Last year, Hunter Biden filed a lawsuit against Ziegler and ten others, accusing them of illegally obtaining and publishing emails, photos, videos, and recordings from his laptop.

Additionally, Biden’s friend Kevin Morris, who loaned him millions of dollars, also sued Ziegler for harassment and doxing.

Ziegler described these lawsuits as “frivolous” and urged Biden to “focus on paying his attorneys.”

When asked why he attended the trial, Ziegler stated it was “prudent” for him to be there.
