It's probably still available on the Net. Just google "President Trump Chris Wallace interview" and you should get a link to the FoxNews video of it.
I'd agree with Trump that Wallace, though he denied it, tends to be pro-Democrat, so he had some disagreements with Trump over some things, like whether Biden endorsed defunding of police. Turns out that Wallace today acknowledged that Biden did that but it was not included in the Biden-Sanders agreement. But Wallace gave him a tough time about it. Trump and Wallace also disagreed about the death rate of COVID in the US as compared to other countries. At one point Kayleigh McEnany came to Trump's aid by producing a statistical sheet supporting the relative low death rate in the US.
I don’t really wanna watch it unless someone tells me Trump kicked ass rather the media narrative that it was very bad. ;d
