These types of investigations should not be made public until they are concluded... Its totally unfair to subject someone to the court of public opinion..
This is formula 1, when do team's or fia learn from prior mistakes...on serious note..will be pretty wild if Horner get him self ousted due to doing something inaproriate, I would think some one who managed to bring his team so far would not do something stupid to only loose it all...especially in current age...
Dutch and british tabloids are now reporting that one factor in Horner losing support could be due to a power struggle between Horner and Marko, which has been brewing behind scenes ever since Mateschitz' death. Apparently Horner wanted to push Marko out of the team at the end of 2024 when Marko's contract runs out.
It would have to be pretty fucking damning and incredibly serious offenses for them to part ways with Horner. The guy just had a record setting season that will go down in F1 history. The last few years of dethroning Mercedes and becoming a juggernaut.
I seriously doubt he has "lost support" at Red Bull...unless he did some off the wall crazy shit.
