WATCH: Hillary Clinton ignores questions about Durham report that confirms her campaign spied on Trump

As Clinton was arriving at her daughter Chelsea's Manhattan apartment mid morning, Laura Collins from the Daily Mail pressed Clinton about the report's allegations.

"Did you pay to spy on the Trump campaign?" she asked. "When are you going to comment on the spying allegations, Hillary?"

Clinton continued to walk, waving at the reporter as she passed.

A Friday court filing by Special Counsel John Durham alleged that Clinton campaign lawyer Michael Sussmann billed the Clinton campaign for his work on the "Russia Bank-1 allegations," involving a tech executive, an investigative firm, and several lawyers linked to the Clinton campaign.

In the motion, Durham claimed that the executive asked researchers to "mine Internet data to establish 'an inference' and a 'narrative' that would tie Trump to Russia."

Following the filing, President Joe Biden's National Security Adviser Jake Sullivan came under scrutiny after it was revealed that Sullivan was the "foreign policy adviser" mentioned in the indictment of Sussmann last fall.

Just days before the 2016 presidential election, Clinton shared a statement from Sullivan on Twitter, coming in response to article in Slate covering a team of computer scientists who claimed to have discovered a link between Trump and Russia-based Alfa Bank.

"This could be the most direct link yet between Trump and Moscow," Sullivan said. "Computer scientists have apparently uncovered a covert server linking the Trump Organization to a Russian-based bank."

He added, "This secret hotline may be the key to unlocking the mystery of Trump's ties to Russia."

In response, Republican are now questioning if Sullivan knowingly promoted faulty information while simultaneously hiding links to his then-boss.

Sussmann's 27-page indictment states that he told then-FBI General Counsel James Baker that he was not working for a client when he requested a meeting where he offered evidence of what he claimed was a secret communication channel between Donald Trump and a Russian bank.

Despite this, the document alleges that Sussmann was being paid by at least two clients, a US technology executive and the Clinton presidential campaign, according to the Daily Mail.

"On or about September 15 , 2016, Campaign Lawyer-1 exchanged emails with the Clinton Campaign's campaign manager, communications director, and foreign policy adviser concerning the Russian Bank-1 allegations that SUSSMANN had recently shared with Reporter1," it says.

According to Fox News, two "well-placed sources" said that Sullivan is the "foreign policy advisor" in question.

Durham's Friday filing revealed how Sussmann "had assembled and conveyed the allegations to the FBI on behalf of at least two specific clients, including a technology executive (Tech Executive 1), named as Rodney Joffe, at a US-based internet company (Internet Company 1) and the Clinton campaign."

It also revealed how Joffe worked with Sussmann at the instruction of the Clinton campaign to "assemble the purported data and white papers."
