The West Wing
Episode 3 ” A Proportional Response”
Last 10 minutes
The President was in a terrible mood and had a lot of things going on and he yelled at Charlie the new kid (the black kid, aide-to-be). After some calming down with the help of Leo the President came back out to the press room. Before addressing the nation he pulled Charlie aside, told him what kind of gun had killed his mother (a police officer), and said the white house was working to get those banned. Then he invited Charlie to join them.
Best moment in TV. I might have teared up a little bit.
