During a recent press conference in the Oval Office, which was intended to focus on nuclear energy, President Donald Trump struggled to silence his ringing phone. This incident is the latest example of the 78-year-old president’s difficulties with technology.

Trump was discussing the tariffs he has imposed on imported goods, which have led to increased prices for many American consumers, when his phone rang during the White House event. In response, Trump joked, “Oh, it’s a phone call, do you mind?” and proceeded to pick up his iPhone.

Trump attempted to answer the call by swiping right on his phone, which is typically how one answers a call, not sends it to voicemail. He then set the phone face-down on his desk, saying, “Okay, it’s only a Congressman.” When a reporter asked who the caller was, Trump replied, “I’d let you know,” but failed to provide any further information.

Less than 10 seconds later, the phone rang again, and Trump picked it up, this time saying, “it’s a different Congressman.” On the second attempt, Trump managed to silence his phone by pressing the side buttons a few times. However, he still did not reveal the identity of the caller.

There is no evidence to suggest that Trump has ever used a computer for work purposes. In 2016, Gizmodo investigated this question and found no indication that Trump had ever sat in front of a computer to do proper work. Instead, Trump dictates his tweets during the day and sends them himself late at night. Additionally, during his trial in 2022, his personal attorney Alina Habba stated that Trump does not use email or text messages.

According to CNN, Habba said, “President Trump does not email. He does not text message. And he has no work computer at home or anywhere else.” Habba is now serving as the acting U.S. Attorney for the District of New Jersey.

Trump’s struggles with technology are well-documented. In March, while promoting Elon Musk’s cars at the White House, Trump famously said, “everything’s computer.” This statement highlights his lack of understanding of the tech-filled world he lives in. Trump has also spoken about cryptocurrencies in an awkward manner, initially expressing opposition to bitcoin before changing his tune when he realized its potential to make him billions of dollars, according to CBS News.

Recently, Trump hosted a dinner for major buyers of his own cryptocurrency, $TRUMP, in a move that has been described as shockingly corrupt. On Friday, Trump threatened to impose a 25% tariff on Apple for moving its production facilities to India instead of the U.S. He suggested that the tariff could start at the end of June and seemed to imply that Apple should have no problem moving its factories to the U.S. since everything is automated.

When a reporter asked how Apple could afford to move its factories to the U.S. without increasing prices, Trump responded, “A lot of it’s so computerized now. These plants are amazing if you look at them.” This comment contradicts his previous statements about the need for companies to move to the U.S. to create jobs. In reality, Trump’s concerns seem to be rooted in his misunderstandings about modern economies and trade deficits.

Trump expressed frustration with Apple CEO Tim Cook, saying that he had an “understanding” about bringing Apple’s plants to the U.S. instead of moving them from China to India. Trump stated, “I said, that’s okay to go to India, but you’re not going to sell into here without tariffs. And that’s what it is.”

Perhaps if Trump were nicer to Cook, the Apple CEO could help the president learn how to silence his phone during important meetings.
