Senate Judiciary Chair Chuck Grassley and Senator Ron Johnson published new emails from FBI whistleblowers showing that President Joe Biden’s then-Deputy White House Counsel Jonathan Su personally assisted the FBI in securing President Donald Trump and Vice President Mike Pence’s cell phones to assist the nascent “Arctic Frost” investigation over January 6.

The new whistleblower emails also show that a future member of Special Counsel Jack Smith’s team and an anti-Trump FBI agent were closely involved in the origins of the FBI probe. Operation Arctic Frost formed the basis of former Special Counsel Jack Smith's false elector case under which former President Donald Trump was later charged with a conspiracy to defraud the United States for his campaign’s attempts to assemble alternate slates of electors under claims that the 2020 election had been stolen.

The new emails are contained in a letter the senators sent to Attorney General Pam Bondi and FBI Director Kash Patel urging cooperation with their requests for all information related to the FBI probe.

“Overall, these newly disclosed emails show the extensive collaboration between and among select FBI agents from the Washington Field Office and prosecutors from the U.S. Attorney’s Office – Washington D.C. to plan, approve and execute Arctic Frost,” Grassley and Johnson wrote. “The emails also provide further support that ASAC Thibault played a central role in advancing its approval to a full field criminal investigation when other agents had concerns the supporting evidence only allowed for a preliminary investigation.”

"Lastly, the emails illustrate the Biden White House’s personal involvement in providing former President Trump and former Vice President Pence’s phones to the FBI at their request when neither of them was a subject of the investigation at that point in time,” they added.

The emails turned over to the committee by whistleblowers show that the U.S. Attorney’s Office Criminal Chief John Crabb emailed Su at the White House on May 2, 2022 and copied Assistant Special Agent in Charge Timothy Thibault.

“Jonathan, Would you please coordinate with Tim Thibault (who's copied on this email) about picking up the telephones,” Crabb wrote.

“Thanks John. Tim, it is good to meet you, and please let me know what works for you in terms of timing the next couple days,” Su replied.

By May 4, other committee records show, the FBI had successfully obtained both President Trump and Vice President Pence’s official phones from the Biden White House, even though then-former President Trump had not yet become a criminal subject of the Arctic Frost probe.

You can read Grassley and Johnson’s letter below:

In a prior letter, the senators revealed that the bureau began its process of acquiring the pair's government phones in April of 2022, Just the News previously reported. The bureau also interviewed key members of the first Trump administration, including his deputy White House Counsel.

In January, Grassley also released whistleblower records showing that Thibault, a former FBI agent known for being anti-Trump, had played an important role in Jack Smith's 2020 election interference case.

Grassley and Permanent Subcommittee on Investigations Chairman Ron Johnson claimed that internal emails and records show that former FBI agent Timothy Thibault, who was fired in 2024 for violating the Hatch Act, sent a subordinate an email that included the language for what ultimately became Smith's false elector case, Just the News previously reported.

The newly published communications, the senators say, show that Thibault “hand-picked subordinate agents, including Michelle Ball and Jamie Garman…to conceal his role as an initiating agent,” from FBI leadership. An email contained in the letter shows Thibault informing a colleague that he assigned the agents to the case as he was trying to get the probe approved by leadership.

The records also show that Assistant U.S. Attorney Thomas Windom, who would later join Jack Smith’s team, had an early role in the development of the probe before he moved to the special counsel’s office.

Emails among FBI staff reference Windom’s work to begin interviewing witnesses or subjects in the case. “He plans to start calling represented persons and serving J sbps,” one agent wrote to Thibault on February 25, 2022. The investigators ended up spending $16,000 to conduct over 40 interviews, serving subpoenas, and executing several device search warrants, Grassley and Johnson previously revealed.

Grassley and Johnson again reiterated their requests for full documents from the Department of Justice and the FBI about the FBI probe.

“In order to conduct our constitutional oversight responsibilities, and to determine who later added former President Trump as a criminal subject to the case, we reiterate our request for your offices to produce all DOJ and FBI records in the Arctic Frost investigation,” they wrote, and set a deadline of April 21, 2025.
