Where is the court ruling showing he was an MS 13 member?
I can't find it - only allegations.
I did find the Supreme Court ruling that the government must facilitate his return. It includes these statements:
Don't you think that if the Trump administration had proof he was an MS13 member that they would have presented that to the SCOTUS?
There was also this:
The United States Government arrested Kilmar Armando Abrego Garcia in Maryland and flew him to a “terrorism confinement center” in El Salvador, where he has been detained for 26 days and counting. To this day, the Government has cited no basis in law for Abrego Garcia’s warrantless arrest, his removal to El Salvador, or his confinement in a Salvadoran prison. Nor could it. The Government remains bound by an Immigration Judge’s 2019 order expressly prohibiting Abrego Garcia’s removal to El Salvador because he faced a “clear probability of future persecution” there and “demonstrated that [El Salvador’s] authorities were and would be unable or unwilling to protect him.” App. to Application To Vacate Injunction 13a. The Government has not challenged the validity of that order.
IF they had such support that Garcia was a gang member and a threat, why didn't they challenge the 2019 ruling in court???
That would have been the proper legal thing to do.
I doubt they had any support regardless of what made up stuff they are coming up with now.
