White house card - I can draw parallels with ufc card in Sphere, that happened on Mexican independance day. There were lots of Mexicans in that card, but main and co-main events were headed by Georgian vs American, Kyrkyz vs Mexican. I think we can get anything from White House card 
And I am not even sure there will be top fighters-stars in the card.
And I am not even sure there will be top fighters-stars in the card. I think the same. It will be a card with many more Americans, that's a fact. However, I still think there will be many fights between Americans, precisely so that no American loses the fight in the White House. But it could very well be like the UFC in the sphere, where it was a show with the majority of Mexicans showcasing their talent.
