President Trump's former social media director recently revealed that his reaction to Trump learning to tweet on his own was "oh no."  Justin McConney, who worked for the Trump Organization from 2011 to 2017, told Politico that he still remembers the day it happened. He noted he'd been tweeting for Trump but came upon a post he hadn't written. McConney said that it was made on February 5, 2013, and read, "Thanks @SherriEShepherd 4 your nice comments today on The View. U were terrific!"  He reportedly asked the staff if they'd sent out the message and learned none had. It soon sunk in that Trump had written and sent that tweet all on his own.  "The moment I found out Trump could tweet himself was comparable to the moment in 'Jurassic Park' when Dr. Grant realized that velociraptors could open doors," McConney told Politico. "I was like, 'Oh no.'" 
Twitter has proven to be a much-used tool for Trump.  In 2017, he told Financial Times, "Without the tweets, I wouldn't be here," and said that, given his large number of followers, "I don't have to go to the fake media." TIME magazine noted early in the year that Trump's tweets do often result in action being taken, though not always the sort he likely intended.  According to the publication, "they have cut the cost of an Air Force contract, undermined White House messaging…stoked a congressional investigation…possibly led to the appointment of a special counsel," and, "created new legal trouble for the White House," and more.
