Yeah, apparently. Just a few hours ago Mexico had a press release saying they do have warrants for him. It's been a rumor for the entire lead up to this fight and people (including me) were wondering WTF he was thinking with the current environment here in the US and Mexico having so much trouble the past few months with cartel violence. They gonna "martyr" him.
edit: he's had a checkered past. Known to dabble in drugs to the point of needing rehab, plus court ordered rehab in the USA, multiple arrests including ghost guns, general debauchery like you might expect from a nepo baby.
