He has never apologized nor retracted that accusation, and Fox News has allowed his unprofessional, unethical behavior to go uncorrected. For me, it's not a question of bias. I don't expect "journalists" to be unbiased.
If he had simply said "They haven't convinced me" or even "I don't believe them" that would be fine. He, however, misused his professional position to publicly slander the Swiftboat Vets, and from that moment I have had no use whatsoever for him. Again, not because of his bias - we're all biased, but because he is professionally unethical, incompetent and negligent.
I didn't know that. Thanks.
