During the recent testimony of ex-Trump assistant Madeleine Westerhout, details about the former president's use of social media while in the White House were revealed. Westerhout confirmed that Trump did use social media, specifically Twitter, and that he personally posted tweets himself.
Westerhout also mentioned that former White House Deputy Chief of Staff Dan Scavino had access to Trump's Twitter account, but she did not believe anyone else had access. She noted that Scavino could post event video recaps without Trump's direct approval, although the president did like to review the tweets that were sent out.
