Facebook CEO Mark Zuckerberg recommended campaign hires to Democratic presidential candidate Pete Buttigieg, Bloomberg reports, in a rare example of the embattled tech leader giving direct advice to a candidate. The exchange between Zuckerberg and Buttigieg lends credence to the idea that Buttigieg won’t go as far as some of his Democratic rivals in calling for Big Tech to be brought to heel.

Zuckerberg emailed Buttigieg’s campaign manager recommending people to hire; two ended up with jobs on the campaign. One worked for Facebook and one worked for Quora. Buttigieg has been in Silicon Valley for high-dollar fundraisers and has said tech may need regulation. But he hasn’t called for breaking up companies, differentiating himself from candidates like Sen. Elizabeth Warren.

Also on the campaign front, the campaign to re-elect President Donald Trump is flooding YouTube, Facebook and other sites with digital advertisements while Democratic presidential candidates are struggling to keep up, the New York Times reported Sunday. In the last 90 days, Trump’s campaign has spent about $5.3 million on Facebook ads.

Trump’s campaign dominated digital advertising in 2016, and if this pattern keeps up, 2020 will be no different.
