Pentagon cracks down on troops' social media posts about Charlie Kirk

Washington: The US military is taking swift disciplinary action against US troops over social media posts linked to the assassination of conservative activist Charlie Kirk, carrying out a "zero-tolerance" policy toward those it sees as cheering his death, US officials said.

The Pentagon has not publicly said how many service members have been disciplined so far but one US official told Reuters it was likely in the dozens, as US military leadership pursues a crackdown ordered by Defense Secretary Pete Hegseth, who knew Kirk personally.

Kirk, a 31-year-old conservative media celebrity known for his hard-right rhetoric, was killed by a single rifle shot during an outdoor event last week at Utah Valley University.

The staunch ally of President Donald Trump was not in the US military's chain of command and had no official role in the US government.

But legal experts and US officials say US troops do not have the same free speech rights as private citizens and can be punished for public-facing comments if commanders determine they violate Uniform Code of Military Justice provisions related to "good order and discipline."

"We WILL NOT tolerate those who celebrate or mock the assassination of a fellow American at the Department of War," Sean Parnell, the top Pentagon spokesperson, wrote on X, in comments reposted by Hegseth.

"It's a violation of the oath, it's conduct unbecoming, it's a betrayal of the Americans they've sworn to protect & dangerously incompatible with military service."

Trump has ordered the Department of Defense to rename itself the Department of War, a change that will require action by Congress.

The Army, Marine Corps and Navy did not immediately respond when asked by Reuters whether they had disciplined U.S. troops over such social media posts.

An Air Force spokesperson said: "As commanders verify inappropriate actions, they are taking the necessary administrative and disciplinary actions to hold service members accountable."

Chilling effect

Three U.S. officials, speaking on condition of anonymity, said disciplinary actions so far have included relieving service members from their positions and other admonishment. While there were no known cases of people being separated from military service entirely, officials did not rule out that it might happen.

"The problem is they have very little protection," said Rachel VanLandingham, a former Air Force lawyer now at Southwestern Law School.

One U.S. official referred to Article 88 of the Uniform Code of Military Justice, which he said clearly prohibited "contemptuous words" against any sitting U.S. president, the defense secretary, Congress and other senior officials.

Matthew Lohmeier, an undersecretary of the Air Force, announced over the weekend his intention to prosecute and remove from service an Air Force senior master sergeant in Florida who made comments about Kirk as well as about Trump. He said the airman's entire chain of command should be investigated.

"Men and women who are guilty of this kind of behavior will not serve in uniform," Lohmeier wrote on X.

While the Pentagon may find clear cases of violations of military law during the crackdown, legal experts caution that it is also creating a chilling effect on what would otherwise be permissible speech by U.S. troops, who are increasingly fearful of being seen as opposing the Trump administration.

VanLandingham said she had spoken to an active duty service member who had just combed through 20 years of social media posts, deleting those that have views not currently supported by Trump and his allies.

"The Department of Defense, from the very top, is telling individuals they cannot have certain thoughts," she said, adding that others will likely be "suppressed by threat of punishment."

One US official, speaking on condition of anonymity, acknowledged a chilling effect on what troops were sharing online. But the official also said troops should watch what they do, particularly on public-facing social media - given the current heated political climate.

"Sharing any kind of hot take when publicly identifiable as part of DoD (is) also dumb," the official added.
