Barack Obama: ‘Think Before You Tweet’

EXCERPT:

OBAMA: "And you see people getting in all kinds of trouble because they just send out some tweet and then they're trying to erase it afterwards. But somebody's screen-shot it and then they're embarrassed. You know your mother and your father knew better, listen to them, don't do things like that."
HOST: "I won't --"
OBAMA: "Think before you speak, think before you tweet, same principle."
