Oscar-winning screenwriter Aaron Sorkin has written a letter to his teenage daughter, urging her to "fight the Trumpsters".

The critically acclaimed writer of the presidency drama The West Wing tells his 15-year old daughter Roxy and his wife Julia to "get out of bed" and "f****** fight" after Wednesday's results.

"The world changed late last night in a way I couldn't protect us from. That's a terrible feeling for a father," Sorkin writes in a letter published on Vanity Fair.

"I won't sugarcoat it - this is truly horrible."

The writer then calls the newly elected President a "thoroughly incompetent pig with dangerous ideas", and warns of the dangers of his "White nationalists, sexists, racists and buffoon" supporters.


"Hate was given hope," he writes.

The screenwriter tells the "Sorkin girls" that "the world took no time to react", and that "economists are predicting a deep and prolonged recession".

He speaks of "fear" and says he would trade "this small fraction of a man for Richard Nixon".

"So what do we do?," he asks.

Sorkin then encourages his daughter and wife to "f****** fight".

"We're not powerless and we're not voiceless. We don't have majorities in the House or Senate but we do have representatives there. It's also good to remember that most members of Trump's own party feel exactly the same way about him that we do," he adds.

Sorkin concludes the letter with a message of dissidence, saying "the battle isn't over, it's just begun".

"Your tears last night woke me up, and I'll never go to sleep on you again."
