WASHINGTON, May 31, (AP): A claim by US Homeland Security Secretary Kristi Noem that an immigrant threatened the life of President Donald Trump has begun to unravel. Noem announced an arrest of a 54-year-old man who was living in the US illegally, saying he had written a letter threatening to kill Trump and would then return to Mexico.

The story received a flood of media attention and was highlighted by the White House and Trump's allies. But investigators actually believe the man may have been framed so that he would get arrested and be deported from the US before he got a chance to testify in a trial as a victim of assault, a person familiar with the matter told The Associated Press.

The person could not publicly discuss details of the investigation and spoke to the AP on condition of anonymity. Law enforcement officials believe the man, Ramon Morales Reyes, never wrote a letter that Noem and her department shared with a message written in light blue ink expressing anger over Trump’s deportations and threatening to shoot him in the head with a rifle at a rally. Noem also shared the letter on X along with a photo of Morales Reyes, and the White House also shared it on its social media accounts.

The letter was mailed to an Immigration and Customs Enforcement office along with the FBI and other agencies, the person said. As part of the investigation, officials had contacted Morales Reyes and asked for a handwriting sample and concluded his handwriting and the threatening letter didn’t match and that the threat was not credible, the person said. It’s not clear why Homeland Security officials still decided to send a release making that claim.

In an emailed statement asking for information about the letter and the new information about Morales Reyes, the Department of Homeland Security said "the investigation into the threat is ongoing. Over the course of the investigation, this individual was determined to be in the country illegally and that he had a criminal record. He will remain in custody.”

His attorneys said he was not facing current charges and they did not have any information about convictions in his record. Immigration and Customs Enforcement’s records show Morales Reyes is being held at a county jail in Juneau, Wisconsin, northwest of Milwaukee. The Milwaukee-based immigrant rights group Voces de la Frontera, which is advocating for his release, said he was arrested May 21. Attorney Cain Oulahan, who was hired to fight against his deportation, said he has a hearing in a Chicago immigration court next week and is hoping he is released on bond.
