Many of Trump’s political allies rushed to his defense on Wednesday.

“Twitter is engaging in 2020 election interference. They are putting their thumb on the scale,” said Florida Republican Rep. Matt Gaetz, a loyal Trump supporter and surrogate during an appearance on the Steve Bannon-produced podcast War Room Pandemic. “The notion that they would outsource fact checking to people who have been wrong about everything is an insult.”

Trump campaign manager Brad Parscale said that his team no longer pays for advertising on Twitter and accused the tech giant of purposefully influencing the election to hurt the President.

“We always knew that Silicon Valley would pull out all the stops to obstruct and interfere with President Trump getting his message through to voters,” Parscale said in a statement. “Partnering with the biased fake news media ‘fact checkers’ is only a smoke screen Twitter is using to try to lend their obvious political tactics some false credibility.”

The President made the decision to warn Twitter despite the fact that the company and most other prominent social media platforms have allowed him and his associates to peddle unsubstantiated conspiracy theories with few constraints. While Twitter added the fact check to Trump’s tweets on mail-in voting, it did not do so on any of his recent tweets baselessly suggesting MSNBC host Joe Scarborough was somehow involved in the death of a former aide, despite a plea from the aide’s widower to take the tweets down.

Trump’s Twitter habits have been the scrutinized for virtually his entire political career, but people familiar with his use of the platform describe less of a strategy and more of a mindset as he or an aide taps out messages.

Other people inside the administration, and even some of Trump’s closest advisers, are regularly caught off-guard by what appears on his feed — if not always surprised.

While his messages often have the effect of distracting from an unfortunate headline, people close to the President say it is their impression that he genuinely believes many of the more conspiratorial things he sends — including debunked theories about his predecessor — and that he isn’t raising them only in the hopes of diverting attention elsewhere.

Trump’s top social media adviser, Dan Scavino Jr., was recently elevated to become one of the highest-ranking officials in the West Wing. His title, deputy chief of staff for communications, belies the fundamental role he plays both in Trump’s use of Twitter and in his life generally. Trump trusts Scavino almost unreservedly. Scavino has worked for the President since before the 2016 campaign when he was a manager at one of Trump’s golf clubs.

Scavino is usually the person who locates the internet content — sometimes from fringe sources and often incendiary — that finds it way to Trump’s Twitter feed, though other friends and advisers have suggested tweets and retweets as well.

Scavino’s West Wing office provides him regular access to the President, as does his near-ubiquitous presence on Trump’s trips, where he is often seen videotaping or photographing the President. He is believed to be the only other person with access to @RealDonaldTrump, though the mechanics of the account have never been confirmed by the White House.

Trump’s tweet rants have always been controversial. But recently, as the US death toll from the pandemic has approached 100,000, they have become uncomfortable even for some of the President’s most prominent supporters.

“I do think the President should stop tweeting about Joe Scarborough in the middle of a pandemic,” said Rep. Liz Cheney, a Wyoming Republican. “He’s the commander in chief of this nation and he is causing great pain to the family of the young woman who died.”

But those who understand the President’s social media habits believe it is unlikely that he will change his behavior any time soon. Miller, who has been present as Trump crafts his tweets, said the President views the platform as an outlet where he can speak directly to his supporters.

“It is one of President Trump’s super powers,” Miller said. “He understood very early on that social media, Twitter in particular, gave him unvarnished access to the American people and his supporters. What Trump maximized was social media’s ability to bypass the artificial conversation created by the mainstream media.”
