Read Facebook CEO Mark Zuckerberg’s Response to Donald Trump’s Election Win

Mark Zuckerberg is feeling “hopeful” after watching election returns with his daughter Max, he said in a Facebook post late Wednesday.

Without getting explicitly political, the Facebook CEO wrote that the election has reminded him “about all the work ahead of us to create the world we want for our children.” The work of curing disease and improving education is a long-term goal, he said, and he urged readers: “Let’s go work even harder.”

“This work is bigger than any presidency and progress does not move in a straight line,” Zuckerberg wrote, coming the closest he would in the post to referencing Donald Trump’s surprising victory.

Earlier on Tuesday, Zuckerberg had posted a photo of his “I Voted” sticker. Zuckerberg didn’t publicly endorse a candidate, but has referenced Trump negatively in the past. “I’m starting to see people and nations turning inward, against this idea of a connected world and a global community,” he said at a Facebook conference in April. “I hear fearful voices calling for building walls and distancing people they label as others.”
