The West Wing creator Aaron Sorkin has penned a letter to his wife and daughter after Donald Trump was elected 45th President of the United States.

The letter was published on Vanity Fair’s website Thursday morning and is a particularly meaningful read given his work on the masterful West Wing series.

“The world changed late last night in a way I couldn’t protect us from,” he says. “That’s a terrible feeling for a father. I won’t sugarcoat it — this is truly horrible. It’s hardly the first time my candidate didn’t win (in fact it’s the sixth time) but it is the first time that a thoroughly incompetent pig with dangerous ideas, a serious psychiatric disorder, no knowledge of the world and no curiosity to learn has.”

Later in his letter, Sorkin offers some glimmers of hope. What can we do? How can we move forward?

First of all, we remember that we’re not alone. A hundred million people in America and a billion more around the world feel exactly the same way we do.

Second, we get out of bed. The Trumpsters want to see people like us (Jewish, “coastal elites,” educated, socially progressive, Hollywood…) sobbing and wailing and talking about moving to Canada. I won’t give them that and neither will you. Here’s what we’ll do…

…we’ll fucking fight. (Roxy, there’s a time for this kind of language and it’s now.) 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. We make sure that the people we sent to Washington—including Kamala Harris—take our strength with them and never take a day off.

We get involved. We do what we can to fight injustice anywhere we see it—whether it’s writing a check or rolling up our sleeves. Our family is fairly insulated from the effects of a Trump presidency so we fight for the families that aren’t. We fight for a woman to keep her right to choose. We fight for the First Amendment and we fight mostly for equality—not for a guarantee of equal outcomes but for equal opportunities. We stand up.

America didn’t stop being America last night and we didn’t stop being Americans and here’s the thing about Americans: Our darkest days have always—always—been followed by our finest hours.

Roxy, I know my predictions have let you down in the past, but personally, I don’t think this guy can make it a year without committing an impeachable crime. If he does manage to be a douche nozzle without breaking the law for four years, we’ll make it through those four years. And three years from now we’ll fight like hell for our candidate and we’ll win and they’ll lose and this time they’ll lose for good. Honey, it’ll be your first vote.

The battle isn’t over, it’s just begun. Grandpa fought in World War II and when he came home this country handed him an opportunity to make a great life for his family. I will not hand his granddaughter a country shaped by hateful and stupid men. Your tears last night woke me up, and I’ll never go to sleep on you again.

Love,

Dad

This writer hopes Sorkin is right about that impeachable crime.
