According to Politico, "President Donald Trump uses a White House cellphone that isn't equipped with sophisticated security features designed to shield his communications." The decision is "a departure from the practice of his predecessors that potentially exposes him to hacking or surveillance." From the report: The president uses at least two iPhones, according to one of the officials. The phones -- one capable only of making calls, the other equipped only with the Twitter app and preloaded with a handful of news sites -- are issued by White House Information Technology and the White House Communications Agency, an office staffed by military personnel that oversees White House telecommunications. While aides have urged the president to swap out the Twitter phone on a monthly basis, Trump has resisted their entreaties, telling them it was "too inconvenient," the same administration official said. The president has gone as long as five months without having the phone checked by security experts. It is unclear how often Trump's call-capable phones, which are essentially used as burner phones, are swapped out.
