She proved she was biased when saying it and a liar by claiming she was sorry for doing so.
lol. biased? maybe you could claim bias if something about the election ended up in front of the court...
and nothing about expressing regret makes one a liar
Don't have to. By saying what she said, she already indicated where she stood. If you think, based on what she said, she would be anything but biased, you're an idiot. Would she be honorable enough to recuse herself since she has proven she wouldn't be able to be impartial?
It does when the only reason you do it isn't sincere.
