Rep. Shri Thanedar, a Michigan Democrat, formally introduced two articles of impeachment against Defense Secretary Pete Hegseth on December 9, 2025, escalating congressional scrutiny of Hegseth's role in a deadly U.S. strike on a suspected drug-smuggling vessel and his use of the Signal messaging app to discuss sensitive military operations.
The resolution, H.Res. 935, accuses Hegseth of "Murder and Conspiracy to Murder" and "Reckless and Unlawful Mishandling of Classified Information." Those are allegations contained in an impeachment resolution, not criminal convictions or findings by a court. The measure was referred to the House Judiciary Committee.
The effort faced a major procedural obstacle from the outset. Republicans held 220 House seats to Democrats' 213 after Rep. Matt Van Epps was sworn in on December 4, leaving two vacancies. House Minority Leader Hakeem Jeffries had also said days earlier that he did not expect the Republican-controlled House to bring impeachment articles against Hegseth to the floor. His comments described the political arithmetic in the chamber, not a formal ruling on the allegations themselves.
What the Articles of Impeachment Allege
Thanedar's resolution combines two separate controversies involving the Defense Department: the September 2, 2025, attack on a suspected drug-trafficking vessel in the Caribbean and Hegseth's handling of sensitive information about U.S. strikes against Houthi targets in Yemen.
The September 2 Caribbean Boat Strike
The first impeachment article concerns a U.S. military operation against a vessel the Trump administration said was transporting illegal drugs. Reporting about the September 2 operation prompted scrutiny after it emerged that two people survived the initial attack and were subsequently killed in a second strike.
Reporting by The Washington Post said Hegseth had issued a directive before the operation to kill everyone aboard. Hegseth and the Pentagon disputed key aspects of that reporting. The White House acknowledged that a second strike occurred but said Adm. Frank M. "Mitch" Bradley, the commander overseeing the operation, directed it within his authority. Hegseth later publicly defended Bradley's decision and said he would have approved the second strike himself.
That distinction matters. The existence of the second strike became established, but the precise nature of Hegseth's instructions and the legal justification for killing the survivors remained disputed. Members of Congress from both parties called for investigation into the operation, including whether the strikes complied with U.S. and international law.
Thanedar's December 9 announcement characterized Hegseth's conduct as murder and conspiracy to murder. That characterization represents the congressman's allegation and had not been established through a criminal proceeding.
The Signal Investigation: What the Pentagon Watchdog Actually Found
The second impeachment article concerns Hegseth's use of Signal, a commercially available encrypted messaging application, to communicate details about planned U.S. military strikes against Houthi forces in Yemen in March 2025.
The controversy began after journalist Jeffrey Goldberg was inadvertently added to a Signal group involving senior Trump administration national-security officials. Hegseth transmitted operational information in the group before U.S. strikes took place.
A subsequent Defense Department inspector general investigation provided a more precise picture than competing political descriptions of the episode. The watchdog found that Hegseth used his personal phone and Signal to transmit sensitive, nonpublic Defense Department information about the forthcoming operation. It concluded that doing so created an operational-security risk that could have resulted in failed mission objectives or harm to U.S. pilots if the information had reached an adversary.
The inspector general also found that using a personal device for official business and transmitting nonpublic Defense Department information through an unapproved commercial messaging application violated department policy. The report additionally identified record-retention problems involving the Signal messages.
At the same time, the inspector general did not conclude that Hegseth unlawfully disclosed classified information. Hegseth argued that, as an original classification authority, he had authority to determine that information was unclassified or to declassify it. The watchdog acknowledged his classification authority while separately finding that his method of transmitting the operational information created security risks.
Hegseth and Pentagon officials described the report as a "total exoneration." Critics, including lawmakers, disputed that characterization because the report documented policy violations and operational-security risks. The underlying findings therefore do not fit neatly into either claim that the investigation proved an illegal disclosure of classified information or that it found no problems with Hegseth's conduct.
Impeachment Does Not Mean Removal
The Constitution gives the House of Representatives the power of impeachment and the Senate the power to conduct impeachment trials. A simple majority of the House can approve articles of impeachment. That action formally impeaches an official but does not by itself remove the person from office.
Conviction in the Senate requires a two-thirds vote of senators present. The Constitution permits impeachment for "Treason, Bribery, or other high Crimes and Misdemeanors." Congress has historically debated the scope of that standard, and impeachment is a constitutional process separate from an ordinary criminal prosecution.
At the time Thanedar introduced H.Res. 935, Republicans controlled the House. That meant the resolution could not advance without either support from Republican members or action by Republican-controlled committees and leadership. Jeffries had already emphasized that political obstacle when discussing the prospect of impeachment on December 1.
Cabinet Impeachment Is Exceptionally Rare
Only two U.S. Cabinet secretaries had been impeached before Thanedar introduced his resolution against Hegseth: Secretary of War William Belknap in 1876 and Homeland Security Secretary Alejandro Mayorkas in 2024. Neither was convicted by the Senate.
William Belknap's 1876 Impeachment
Belknap served as secretary of war under President Ulysses S. Grant. A House investigation uncovered evidence of a corruption scheme involving payments connected to a lucrative military trading post.
On March 2, 1876, Belknap resigned shortly before the House was scheduled to consider impeachment. His resignation did not end the proceeding. The House unanimously approved five articles, and the Senate later determined that it had jurisdiction to try him even though he had already left office.
According to the Senate Historical Office, a majority of senators ultimately voted to convict Belknap on each article, but none of the votes reached the constitutionally required two-thirds threshold. He was therefore acquitted.
The Belknap episode remains an important historical precedent because it demonstrates both the extraordinary rarity of Cabinet impeachment and the constitutional questions that can arise when an official resigns before proceedings are completed.
Mayorkas in 2024
Nearly 148 years later, Homeland Security Secretary Alejandro Mayorkas became the second Cabinet secretary impeached by the House.
On February 13, 2024, the House approved H.Res. 863 by a 214-213 vote. The articles accused Mayorkas of "willful and systemic refusal to comply with the law" and "breach of public trust" in connection with immigration and border policy. Democrats rejected those accusations and argued that policy disagreements did not satisfy the constitutional standard for impeachment.
When the articles reached the Senate in April 2024, the Democratic-controlled chamber dismissed both without conducting a full evidentiary trial. Senators divided sharply over whether the allegations constituted impeachable offenses.
The Mayorkas episode illustrates another important distinction: House approval of impeachment articles does not guarantee either a lengthy Senate trial or removal from office.
Why Hegseth's Case Faced a Difficult Path in the House
When H.Res. 935 was introduced, the House had 220 Republicans and 213 Democrats, with two vacancies. Assuming every sitting Democrat supported impeachment, passage would still require Republican votes.
But party affiliation alone did not determine lawmakers' views of the underlying controversies. Republican members of Congress had joined Democrats in seeking additional information about both the Caribbean strikes and Hegseth's handling of sensitive operational information.
That bipartisan interest in oversight did not automatically translate into support for impeachment. Lawmakers can investigate executive-branch conduct through committee hearings, subpoenas, inspector general reviews, legislation and other oversight mechanisms without supporting removal of an official.
Jeffries made that distinction in his December 1 remarks. Rather than predicting that an impeachment vote would succeed, he pointed to investigations by the House and Senate Armed Services committees as the more immediate avenue for examining the boat strikes.
What H.Res. 935 Actually Changed
Thanedar's filing formally placed allegations against Hegseth into the congressional impeachment process. It did not establish that Hegseth committed murder, committed a war crime or unlawfully disclosed classified information. Those remained allegations requiring separate factual and legal analysis.
Nor did introduction of the resolution mean the House would vote on impeachment. The resolution was referred to the Judiciary Committee, and further action depended on the House's procedures and political leadership.
The controversies surrounding Hegseth nevertheless involved issues broader than the impeachment resolution itself: congressional oversight of military force, the legal framework governing attacks on suspected drug-trafficking vessels, operational-security rules for senior officials and the handling of sensitive military communications.
History provides relatively few Cabinet impeachment cases from which to draw comparisons. Belknap was impeached but acquitted after resigning, while Mayorkas was impeached but saw the Senate dismiss the articles. Hegseth's case entered that unusual constitutional territory with an additional obstacle: the party controlling the House was also the party of the president who appointed him.
