Defense Secretary Pete Hegseth is facing another significant challenge as yet another military commander has decided to leave his post amid widespread resignations within the department.

Navy Admiral Alvin Holsey announced that he will be stepping down in December, cutting short his tenure by two years, as his original contract was set to span three years.

“It has been a tremendous honor to serve as your commander and deputy for the past 34 months,” Holsey stated, expressing his sentiments upon announcing his departure.

This development represents a significant setback for Hegseth, who has been under increasing scrutiny due to a series of personnel exits and leaks from within his department.

Admiral Holsey, known for his leadership in the department’s efforts to combat narcoterrorism, reportedly experienced growing tensions with Hegseth concerning operations in the Caribbean, according to insider sources.

Holsey’s announcement comes in the wake of a recent U.S. military operation on Thursday, targeting a suspected drug-trafficking vessel in the Caribbean.

Three members of the crew appear to have survived.

The US military launched search and rescue assets, but it was not clear if any survivors were rescued, according to Fox News.

His departure is a bitter blow for Hegseth, who has faced mounting pressure after a wave of departures and leaks from his department

Prior to Thursday’s operation, US military strikes against suspected drug boats off Venezuela killed at least 27 people, raising alarms among some legal experts and Democratic lawmakers, who question whether they adhere to the laws of war.

The Trump administration argues the US is already engaged in a war with narcoterrorist groups from Venezuela, making the strikes legitimate.

But sources told The New York Times that Holsey had expressed concerns about the escalating attacks on alleged drug boats.

One source said Holsey had questioned whether he would be fired as Hegseth sought to clear out the Pentagon. 

He reportedly fired former head of the US Defense Intelligence Agency Lt. Gen. Jeffrey Kruse back in August, as well as Vice Adm. Nancy Lacore, who was chief of the Navy Reserve and Rear Adm. Milton Sands, a Navy SEAL officer who oversees Naval Special Warfare Command.

The administration also stripped security clearances from additional current and former national security officials.

The top Democrat on the Senate Armed Services Committee, Senator Jack Reed, called Admiral Alvin Holsey’s unexpected resignation troubling given mounting fears of a potential US confrontation with Venezuela. 

‘Admiral Holsey’s resignation only deepens my concern that this administration is ignoring the hard-earned lessons of previous U.S. military campaigns and the advice of our most experienced warfighters,’ Reed said.

The US military carried out a new strike on Thursday against a suspected drug vessel in the Caribbean, and in what is believed to be the first such case, there were survivors among the crew.

Holsey became the leader of U.S. Southern Command only in November, overseeing an area that encompasses the Caribbean Sea and waters off South America. 

These types of postings typically last between three and four years.

He said he was ‘honored to serve our nation’ over 37 years in a moving social media statement paid tribute to his team.

‘The SOUTHCOM team has made lasting contributions to the defense of our nation and will continue to do so,’ he wrote. 

‘I am confident that you will forge ahead, focused on your mission that strengthens our nation and ensures its longevity as a beacon of freedom around the globe,’ he wrote.

The department has been targeting vessels suspected of carrying drugs into the United States.

Videos presented by the Trump administration of previous attacks showed vessels being completely destroyed, and there have been no prior accounts of survivors.

The strikes come against the backdrop of a US military buildup in the Caribbean that includes guided missile destroyers, F-35 fighter jets, a nuclear submarine and around 6,500 troops as President Donald Trump escalates a standoff with the Venezuelan government.

Special operations helicopters, B-52s and C-17s are among the aircraft the US has built up in the region, The Washington Post reported.

On Wednesday, Trump disclosed he had authorized the Central Intelligence Agency to conduct covert operations inside Venezuela, adding to speculation in Caracas that the United States is attempting to topple Venezuelan President Nicolas Maduro.

In a letter to the United Nations’ 15-member Security Council Venezuela’s UN Ambassador Samuel Moncada asked for a UN determination that the US strikes off its coast are illegal and issue a statement backing Venezuela’s sovereignty.

Less than a week ago, the Pentagon announced its counter-narcotics operations in the region would not be led by the Miami-based Southern Command, which oversees US military activities in Latin America.

Instead, the Pentagon said a taskforce was being created that would be led by II Marine Expeditionary Force, a unit capable of rapid overseas operations that is based at Camp Lejeune in North Carolina.

That decision came as a surprise to US military-watchers, since a combatant command like Southern Command would normally lead any high-profile operations.
