Fallout From Capitol Siege

The ripple effects of the mob attack in Washington continue to be felt in New York as the authorities investigate those involved, and as officials brace for renewed threats.

On Tuesday, the son of a Brooklyn judge was arrested in connection with last week’s Capitol riot. New York City said it was reconsidering its ties with the Trump family business. And a Republican congressman from New York announced that he would vote to impeach the president on a charge of inciting the riot.

Here’s what else you need to know:

The judge’s son, Aaron Mostofsky, was taken into custody in Brooklyn. His father, Steven Mostofsky, sits on the Kings County Supreme Court.

The younger Mr. Mostofsky was seen in fur pelts and a bulletproof vest as he breached the Capitol last week. He is facing four charges, including stealing government property, which carries a maximum sentence of 10 years in prison.

The authorities were investigating a handful of New Yorkers who had acknowledged being at the riot, including a Metropolitan Transportation Administration employee, William Pepe, who was arrested in White Plains on Tuesday afternoon.

Many New Yorkers had severed ties with the president’s family’s real estate company, the Trump Organization, long before the siege, but this week Mayor Bill de Blasio confirmed that the city was weighing whether to cancel its contracts with the company. Those contracts include ice-skating rinks and a carousel in Central Park, and the Trump Golf Links at Ferry Point.

On Monday, State Senator Brad Hoylman, a Manhattan Democrat, made a request to the state court system to begin the process of stripping President Trump’s personal lawyer, Rudy Giuliani, of his law license. The call came hours after the New York State Bar Association said it was investigating Mr. Giuliani, the former New York City mayor.

Also, Representative John Katko, a moderate Republican in a Democratic-leaning district in central New York, became the first House Republican to publicly say he would vote to impeach President Trump.

“To allow the president of the United States to incite this attack without consequence is a direct threat to the future of our democracy. For that reason, I cannot sit by without taking action. I will vote to impeach this president."

Mr. Katko said in a statement on Tuesday afternoon.
