Uber CEO Travis Kalanick is looking for a second-in-command, according to The Information (paywall). Last week, after a tape surfaced of an argument with an Uber driver, the CEO announced that he needs "leadership help and I intend to get it.” This new position would help Kalanick make key decisions for the beleaguered company. Uber also lost a second exec in a week on Friday — Ed Baker, VP of product and growth.

Upcoming policy moves: President Trump is expected to sign a revised travel ban today. Although it will likely still face court challenges, “the changes are meant to put the order on stronger legal and political footing and are the result of greater collaboration among government agencies than preceded the first order,” explains The Wall Street Journal. Also expected this week: Republicans are planning to introduce their Obamacare replacement bill in the House.

Internet trolls: They’re just like us. New research finds that the most likely time for people to turn into online trolls are Sunday and Monday nights, between 10pm and 3am, and that “a significant proportion of trolling comes from people who haven’t trolled before.” Trolling tends to align with people’s moods, the research finds, and it has a pile-on effect: “Being trolled in another comment thread, or seeing trolling further up in a thread, makes people more likely to join in.”
