Walker has been an extremely vocal supporter of his 'Celebrity Apprentice' boss -- previously telling TMZ Sports he believes Trump will "save America."
Now, with Mitt Romney blasting Trump this morning as a "phoney" who is dangerous for the country -- and John McCain also denouncing him -- Walker went to bat for Donald with a new statement:
"McCain and Romney lost the playoffs years ago yet they want to talk about someone getting ready for the Super Bowl ... Think about that."
By the way, Walker's not the only 'Celeb Apprentice' star who's stood by The Donald -- Terrell Owens, Gary Busey and Stephen Baldwin are also team Trump.
