The cemetery is run by the Dept of Army. Yes they have rules and one is not to make it political
An Arlington National Cemetery official was “abruptly pushed aside” in an altercation with former President Donald Trump’s staff during a wreath-laying ceremony to honor service members killed in the Afghanistan War withdrawal, but she declined to press charges, an Army spokesman said Thursday.
The Army spokesman said the cemetery employee was trying to make sure those participating in Monday’s wreath-laying ceremony to mark the third anniversary of the attack were following the rules, which “clearly prohibit political activities on cemetery grounds.”
So Trump was filmed while at the location. When an employee tried to intervene. They pushed him or her away. Then used the video for political purposes.
A TikTok video of the visit that was later shared by Trump shows scenes of him at the cemetery and includes a voiceover of the Republican presidential nominee blaming the Biden administration for the “disaster” of the Afghanistan withdrawal.
So yeah trump made it political, He was in a video that was being made of his visit and later broadcasted.
He was invited but now they know Trump will make it political with an election come up soon.
