From Newsweek:
Just over a week after the release of the Department of Defense’s first batch of UFO files, President Donald Trump shared an AI-generated photo of himself walking next to a handcuffed alien on Truth Social on Sunday night, sparking confusion on social media over its meaning.
The image shows the president walking next to a tall, gray humanoid in front of what looks like a military site. The alien appears to be tied by the wrists and ankles, though the chain linking the handcuffs is not connected to one of them.
