Keyboard warriors is a normally derogatory reference to aggressive social media trolls—the core of the president's fan base. What agencies did to draw the ire of Trump is unclear. It's possible Trump's snark was directed at campaign manager Brad Parscale, the founder of agency Parscale Digital, with whom he's had a rocky relationship over the past few weeks. Trump's been looking to shake up his campaign and had been reaching out to ad agencies before the start of the pandemic. That's according to one executive at a well-known New York shop that he says was approached by the president late last year. It's possible Trump is being rejected by industry folk—the anonymous exec says his agency turned Trump away. Anyway, we might never know what specific event prompted Trump to take a jab at agencies on Twitter, where he airs all his dirty laundry. Guess everyone's time will come, as Chrissy Teigen found out last year.
