BOR is anti-Trump from the way I hear him speak about Trump. There are a handful that support Trump or at least give him a fair shake, 95% of the rest of the network has it in for him, including Murdoch and Ailes.
O’Reilly should’ve recused himself from the election because he’s Trump’s personal friend and clearly has had a pro-Trump slant since this election started. Although he does try to force himself to be fair to other candidates, sometimes more successfully than other times.
