Sens Carper, McCaskill want answers about security of Trump's phone

President Donald Trump's smartphone and tweets are now the subject of a Senate inquiry. Sens Tom Carper (D-DE) and Claire McCaskill (D-MO) sent a letter to the Secretary of Defense requesting answers on whether President Trump is using an encrypted smartphone in office, or an unsecured personal device. "The national security risks of compromising a smartphone used by a senior government official, such as the President of the United States, are considerable," the senators wrote in the letter. The letter cites multiple reports, which claim President Trump has continued to use his "old, unsecured Android phone." Many of the tweets posted from Trump's personal account, @RealDonaldTrump, since taking office are also marked as coming from "Twitter for Android."
