A week in which some lawmakers tried to overturn an election and President Trump incited a mob to storm the Capitol ended with Twitter permanently suspending Mr. Trump’s account on Friday night, citing “the risk of further incitement of violence.” Around the same time, Parler, a social media platform with more permissive moderation that could serve as the president’s new digital soapbox, faced bans from Apple’s and Google’s app stores.

As the DealBook newsletter has been asking all week: What is the role of business in a moment like this?

To further reflect on this for our weekend edition, we spoke with Lloyd Blankfein, the former Goldman Sachs chief executive who has a history of taunting Mr. Trump on Twitter, about the expectations placed on business leaders, their role in enabling Mr. Trump and, as Mr. Blankfein put it, “What good could come of this?”

That conversation is followed by one with Judy Samuelson of the Aspen Institute, whose timely new book on the “new rules of business” explores responsible corporate citizenship. The interviews have been edited and condensed.
