Looks like it's part of the revenge campaign against MTG's revolt and crusade to release the Epstein files. Milo worked closely with her, and according to this (poorly sourced) article, Laura Loomer recently reported him for being in the country illegally:
Conservative activist Laura Loomer celebrated Yiannopoulos' detention on Friday.
“I was the first person to report on the fact that Milo was in the US illegally, where he incited violence against President Trump and worked for Marjorie Traitor Greene,” she wrote. “Recently, Candace Owens invited this illegal alien into her home. When Milo called for me to be assassinated, I reported him to ICE and the FBI. I told you all that Milo was an illegal alien.”
She added, “Milo is going to be deported back to the UK, where he can live among the Muslims he has recently chosen to embrace. Today is a great day for America.”
It's meant to strike fear into the fracturing GOP influencer base. Candance Owens is next on the list. Anyone else who worked for MTG is likely to become a target as well.
Evil always eats its own.
