The Department of Justice (DOJ) has issued a subpoena for the personal phone records of Jim Jordan, the Chairman of the House Judiciary Committee, as part of the investigation into the January 6 Capitol riot. This subpoena, which covers a period from January 1, 2020, to the present, is one of the most extensive known to target members of Congress during the Arctic Frost investigation, which has led to election-related charges against former President Donald Trump. The subpoena includes a one-year gag order and seeks details on the timing and recipients of Jordan's communications, though it does not include the content of those communications. Jordan, a supporter of Trump, has criticized the DOJ's actions as a breach of the separation of powers, particularly under the Constitution's speech or debate clause. Other lawmakers, including former House Speaker Kevin McCarthy, have also had their phone records requested.

In a separate case, federal prosecutors have indicated that additional charges may be filed against John Bolton, former national security adviser under Trump. This development follows a hearing on November 21, 2025, where prosecutors discussed the review of classified materials retrieved from Bolton's residence and office. The timeline for discovery is expected to extend into the summer of the following year, as the intelligence community must first evaluate the evidence before Bolton's defense team can access it.

Additionally, former President Bill Clinton and former Secretary of State Hillary Clinton have been ordered to testify before the House Oversight Committee regarding their connections to Jeffrey Epstein. This decision comes after their legal counsel sought to provide written statements instead of in-person testimony, which was denied by the committee's chairman. Bill Clinton is scheduled to testify on December 17, while Hillary Clinton will appear on December 18. The subpoenas were issued following bipartisan support and are part of a broader investigation prompted by directives from Trump, who has called for scrutiny of the Clintons' ties to Epstein. While flight records indicate Bill Clinton traveled on Epstein's private jet, there is no evidence linking Hillary Clinton to Epstein, and both have denied any wrongdoing.

Former FBI Director James Comey is also facing legal challenges as he seeks to dismiss a criminal case against him, claiming significant errors in the grand jury process. Comey has been indicted on charges of lying to Congress and obstructing a congressional proceeding. His defense team argues that the indictment lacks legitimacy due to procedural issues, including allegations of misconduct by the interim U.S. Attorney, Lindsey Halligan. U.S. Magistrate Judge William Fitzpatrick has noted a "disturbing pattern of profound investigative missteps" in the handling of the case, raising concerns about the integrity of the judicial process in politically sensitive matters. Comey has pleaded not guilty to the charges, and a ruling on Halligan's appointment is expected soon.
