President Trump's refusal to give up his iPhone sets dangerous precedent

President Donald Trump’s reported refusal to give up his personal iPhone demonstrates the complications of keeping government officials secure at a time when they are increasingly tied to their phones by the time they take office. President Trump reportedly uses three phones -- two secured by the National Security Agency and one personal iPhone that the report says is "no different from hundreds of millions of iPhones in use around the world." But this problem may not be unique to President Trump -- and instead highlights a long-lasting security challenge likely to face future presidents, too. Security officials in any future White House are likely to contend with even more smartphone-addicted presidents. As a new crop of younger, tech-savvy candidates eyes the White House in 2020, President Trump may have set a dangerous precedent by clinging to his preferred phone.
