Trump posted an uncharacteristically lukewarm tweet after meeting with Facebook CEO Mark Zuckerberg this week.

On Thursday, Trump shared a photo of himself and Zuckerberg captioned with: “Nice meeting with Mark Zuckerberg of @Facebook in the Oval Office today.”

The unannounced meeting was first reported by Axios on Thursday. A spokesperson for Facebook told Axios that Zuckerberg was in Washington DC to meet with policymakers to talk about internet regulation. This comes as Facebook faces ongoing pressure from regulators and lawmakers over privacy on the platform.
