A twenty-year-old Chicago man now sits at the center of a case that exposes how far the federal government will stretch obstruction laws when it cannot yet prove a terror plot.
Story Snapshot
- Federal prosecutors say a Signal group admin tried to wipe evidence of a violent White House UFC attack plot.[7][8]
- The defense says the chat was about survivalism and camping, not drones, snipers, and explosives.[3]
- Mercado is charged only with obstruction of justice, yet faces up to twenty years in prison.[7][8]
- The case shows how “domestic terrorism” prosecutions often hinge on messages and intent, not actual violence.[9][10]
How a private group chat became a federal terror-adjacent case
Federal agents say Alexander Iniguez Mercado did more than hang out in a group chat; they say he helped run Signal messaging groups where others talked about a violent attack on a June 14 Ultimate Fighting Championship event at the White House.[7][3] According to the indictment, members discussed using small drones with explosives and snipers to target government officials and wealthy guests.[3][8] That alleged plot never happened. But the chat itself is now treated like the crime scene.
The Department of Justice states Mercado was an administrator and member of those Signal groups, not just a passive observer.[7] Prosecutors also link him to a broader investigation that has already produced seven other defendants, making him the eighth person charged in connection with the alleged plan.[8] In this case, though, he is not charged with conspiracy to commit terrorism. He is charged only with obstruction of justice under a federal statute aimed at evidence destruction.[7]
What happened after the FBI called
One day before the planned event, the Federal Bureau of Investigation called Mercado to talk about online threats tied to the White House UFC card.[8] Prosecutors say he denied any plan to travel to Washington and refused to meet in person.[7][8] Right after that call, according to court documents, Mercado uninstalled the Signal app from his phone.[7] That single act—deleting an encrypted chat app—is what the government now calls obstruction.
The indictment claims that by removing Signal, Mercado knowingly destroyed and concealed electronic data related to the investigation.[7] Under Title 18, United States Code section 1519, it is a federal crime to alter, destroy, or hide records to influence or obstruct a federal matter.[7] That statute was built for shredding documents and erasing hard drives. Today, it is being applied to a twenty-year-old tapping “uninstall” on his smartphone after a tense call with the FBI.[8]
The charge, the stakes, and the missing pieces
Mercado has pleaded not guilty and now faces a maximum of twenty years in federal prison if convicted of obstruction of justice.[8] That is a stunning number when you consider he is not accused of firing a shot, flying a drone, or placing a bomb. Prosecutors do not present any drones, explosives, or weapons tied to him.[3][4] They rely instead on his alleged role as a Signal group administrator and on the timing of his decision to delete the app.[7]
Court filings also state that Mercado warned a high-level co-conspirator, still not caught, that the Federal Bureau of Investigation was investigating them.[8] If true, that tipoff fits squarely within what obstruction laws were meant to punish. But there is no public statement or testimony from that co-conspirator to confirm the warning.[3] Agents have also not recovered the deleted Signal messages from his phone, leaving the actual content of his chats unknown.[7]
The defense story: survivalism, fear, and intent
Defense attorneys tell a very different story. They say the Signal group focused on survivalism and camping, not attacking the White House.[3] One lawyer told the court that Mercado “freaked” after someone made an offhand comment about survivalism in the chat.[3] From that view, deleting Signal was the panicked reaction of a scared young man, not the calculated move of a terrorist trying to cover his tracks. That argument aims straight at the core question: what was in his mind when he hit delete?

The Justice Department’s own press release reminds the public that “an indictment merely contains allegations” and that every defendant is presumed innocent until proven guilty beyond a reasonable doubt.[8] Those words matter here because so much of the case turns on intent, not on physical acts. Without the actual messages, jurors will be asked to infer his purpose from his admin role, his refusal to meet the Federal Bureau of Investigation, and the timing of the app removal. That is a thin but powerful narrative frame.
Domestic terrorism, messaging apps, and a gray legal zone
Mercado’s case lands inside a larger trend in domestic terrorism prosecutions. There is no specific federal crime called “domestic terrorism,” so prosecutors reach for other statutes—conspiracy, obstruction, material support—and stretch them to cover alleged plots.[10][11] Legal scholars have shown that many post-September 11 terrorism cases rest on online speech, stings, and preparatory acts rather than completed violence.[9][15] Courts have rarely sided with defendants who claim entrapment or lack of intent.[9]
Media coverage already frames this case as a “foiled terror plot” involving drones and snipers, often treating allegations as facts and barely noting the presumption of innocence.[1][3] Commentators on social media have gone further, calling Mercado a terrorist based only on the charge.[2] From a common-sense conservative view, protecting the country from real attacks is essential. But there is also a duty to make sure a young man is not turned into a political trophy when the hardest evidence is a deleted app and a disputed chat about survivalism.
