No, its a massive revelation from Maduro himself. Not at all misleading or a nothingburger.

"I say to President Donald Trump, with all due respect, ask the FBI and the DEA for the reports from the last four years in Colombia, so you can see who financed, who moved, and who directed the Tren de Aragua—who took them to Colombia and then to the United States."

Here he is admitting that someone moved the gangs into the US. He says there are reports proving who financed and directed these orders at the FBI and DEA. Trump always posts teasers to stuff he already knows. This is him sharing confirmation of what is about to be revealed.
