Can anyone tell me the best action for the following scenario?

You have AA on the button.
2 players call bb and then the next player raises 3x and is called by the player to his left.
The bet is yours and you 3 bet 3x the raise x 2 for the players that raised.
Sb and bb fold as do the two nit callers.
Then the raiser pushes all in as does the player on his left.
The pot is now around 35000.
What is the best action to take at this point.
Call or fold?
What are the odds of a good outcome if any?
You have 40000 for your stack.
You need to call 16000 to play.
Your equity stake is 2400 in the pot so far.
