I'd have preferred to hear a reply like "I'm disappointed that the president chose this solemn event to continue his partisan attacks on his opponents. If he can't set aside his animosity today, how can we expect to work with him tomorrow in good faith?"
Punch back, anywhere and everywhere that Obama does.
