The push by US House Democrats to impeach Defence Secretary Pete Hegseth comes amid growing scrutiny of the Donald Trump administration’s handling of the Iran war.

The move has revived familiar debates in Washington over war powers, civilian casualties and the limits of executive authority.

On Wednesday, a group of Democratic lawmakers led by Yassamin Ansari introduced six articles of impeachment against Hegseth, accusing him of “high crimes and misdemeanours” tied to both military decisions and internal conduct.

Here’s a breakdown of what’s in the impeachment push and what happens next.

What are the six charges?

The resolution lays out six separate accusations, each targeting a different aspect of Hegseth’s role as Defence Secretary.

The first article centres on what Democrats call an “unauthorised war against Iran”, arguing that US military action was launched without approval from Congress. Lawmakers say Hegseth backed plans that exposed American troops to unnecessary risks, including the possibility of ground operations.

The second article focuses on alleged violations of the laws of war. It points to civilian casualties and damage to infrastructure in Iran, including a strike on a girls’ school in Minab that reportedly killed at least 175 people, according to The New York Times. Ansari has accused Hegseth of committing a war crime over the incident. The charge also flags so-called “double tap” strikes and rhetoric suggesting a lack of restraint in military operations.

The third article shifts to national security concerns, accusing Hegseth of mishandling sensitive military information. It refers to a controversy involving discussions about US strikes in Yemen being held on the messaging app Signal, where a journalist was accidentally added to a chat.

The fourth article alleges that Hegseth obstructed congressional oversight by withholding details about military operations, particularly around civilian casualties in Iran and Venezuela.

The fifth accuses him of abusing power and politicising the military. Democrats claim he interfered in personnel decisions, influenced military actions for political reasons and supported investigations into elected officials, including Senator Mark Kelly.

The sixth and final article argues that his actions have damaged the reputation of the US military. It cites criticism of NATO allies, uncertainty over US defence commitments and internal policy decisions affecting transgender service members.

How has the administration responded?

The White House and Pentagon have dismissed the impeachment effort as political theatre. Officials say Hegseth is doing an “outstanding job” and argue the resolution is an attempt by Democrats to generate headlines rather than a serious constitutional move.

Pentagon Press Secretary Kingsley Wilson called the effort a “charade”, insisting the administration had achieved its objectives in Iran.

Why are Democrats targeting Hegseth?

Hegseth’s central role in the Iran conflict has made him a key target for criticism, especially over claims that the war bypassed Congress and caused civilian harm.

The move also fits into a broader Democratic strategy of using institutional tools to challenge the administration. Similar efforts have been directed at other senior officials in the past, even if they did not gain traction.

At the same time, the impeachment articles allow Democrats to formally put their objections on record, particularly on questions of legality and international norms.

Why is the effort unlikely to succeed?

Despite the strong language, the impeachment push faces a steep political hurdle. Republicans hold a slim majority in the House of Representatives and also control the Senate, making it difficult for Democrats to secure the numbers needed.

In the US system, impeachment requires a simple majority in the House but a two-thirds majority in the Senate for conviction. Without bipartisan support, removal from office is highly unlikely.

There is also little indication that Democratic leadership wants to escalate the issue further ahead of the midterm elections, which limits the chances of the effort gaining momentum.
