President Trump has dismissed attempts by White House staffers to enhance security on his cellphones, according to a report.

Trump has at least two iPhones — one for phone calls and another for Twitter and news sites — that were issued to him from White House Information Technology and the White House Communications Agency, Politico reports.

Trump has pushed back on aides encouraging him to change his Twitter phone more regularly, saying his current phone was “too inconvenient,” one official told Politico.

Staff recommended that his phone be swapped out every month, but Trump has used the device for up to five months without having security experts check it.

It’s not certain how frequently the phone Trump makes calls on is looked at. That device also has a camera and a microphone, which means it could be vulnerable to hackers seeking to observe Trump. Even so, the GPS program on both phones has been disabled.

Trump's lax approach to security marks a shift from previous administrations. For example, former President Barack Obama's phones were monitored every 30 days.
