Sounds like Alpine is the only team that's willing to accept the Andretti team's proposed entry.  Makes sense for them as the Andretti team plans to initially use the Renault engine.  Surprised that Zak Brown withdrew his support, but I'd wager Mercedes pressured him to do so as Mercedes is very vocal about their being against the Andretti/Cadillac team.  Certainly the FIA is all for the Andretti team.
