I think it's unreasonable to take the literal meaning od 'anytime, anywhere'. Like, if he was attending a funeral and the senator turned up and challenged him there, would that still be appropriate? How about if he was visiting a kindergarten? While he's helping an old woman cross the road? Performing first aid on an injured person?
There are still times that are appropriate and not appropriate. You could say that the challenge itself was childish and I would agree. But the anytime, anywhere condition doesn't make it unconditionally ok for the senator to pick this time and place.
