Justin McConney served as the social-media director for the Trump Organization from 2011 to 2017.

He used to draft and send out tweets for Trump before teaching him how to do it himself.

McConney suggested that Trump should lighten up on the platform and have "more of a sense of humor about himself."

President Donald Trump's former social-media director said his first reaction to learning Trump could tweet on his own was "oh, no," comparing it to velociraptors learning to open doors in "Jurassic Park."

Justin McConney opened up about teaching Trump to tweet in an interview with Politico published on Thursday.

He served as the social-media director for the Trump Organization from 2011 to 2017 and originally drafted and sent all of Trump's tweets until he learned the president could do it himself.

"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 in an interview. "I was like, 'Oh, no.'"

Trump's first tweet was simple, with him thanking actress Sherri Shepherd for her comments about him on "The View" in 2013.

McConney, who was 24 when he first got Trump to start using Twitter, told Politico that he wanted to develop Trump's brand on Twitter and other social-media platforms.

"I wanted the Donald Trump who is on Howard Stern, commenting on anything and everything," he said.

He said initially, Trump had him print out Twitter mentions, and he would write his responses in Sharpie before handing the messages to McConney to type up and send out.

When he was on "The Apprentice," Trump would phone in his tweets to McConney, even dictating the punctuation.

Despite not knowing much about the new technology, Trump "knew PR and he knew news cycles very well," McConney said.

Once he could tweet on his own, Trump started to weigh in on a number of topics and even feuded with Rosie O’Donnell and former Yankee Alex Rodriguez.

Now, Trump uses the app to tweet an astounding number of times a day. He tweets about his border wall, the "fake news" media, the special counsel Robert Mueller's "Witch Hunt," and his views on other political leaders. The tweets often begin early in the morning, and, pundits have noticed, are often tied to whatever's being covered on Fox News.

McConney suggested that Trump should lighten up on the platform.

"[He] should go back to having more of a sense of humor about himself," McConney said.
