New York Times: “Facebook is preparing steps to take should Mr. Trump wrongly claim on the site that he won another four-year term, said the people, who spoke on the condition of anonymity. Facebook is also working through how it might act if Mr. Trump tries to invalidate the results by declaring that the Postal Service lost mail-in ballots or that other groups meddled with the vote, the people said. Mark Zuckerberg, Facebook’s chief executive, and some of his lieutenants have started holding daily meetings about minimizing how the platform can be used to dispute the election, the people said. They have discussed a ‘kill switch’ to shut off political advertising after Election Day since the ads, which Facebook does not police for truthfulness, could be used to spread misinformation, the people said.”
