Just to add to Donald Trump’s increasingly full plate of political troubles, House Democrats are now pushing for an investigation into the new president’s tendency to practice weak security measures. The representatives are becoming increasingly concerned that President Trump is not taking security seriously and is risking national interests in the process.

It’s well known at this point that Trump is still using an old, commercial-grade Android phone to Tweet with. He even used it to receive an important call with sensitive information right after North Korea conducted missile tests, Ars Technica points out. This is just one among many complaints that intelligence officials have had about him during his less than one month of tenure as president.

As a result, Los Angeles County, California Representative Ted Lieu along with fourteen representatives from his Party sent a letter to both Jason Chaffetz, the chairman of the Oversight Committee and Elijah Cummings, a ranking Democratic member. The letter directly talks about President Trump’s inadequate security practices.

“Referring to the complex problem of cybersecurity, President Trump recently said in an interview, ‘I’m not sure you have the kind of security that you need’,” the letter reads. “We fully agree—which is why we are writing to request that the House Oversight and Government Reform Committee hold a hearing into troubling reports that the President is jeopardizing national security by egregiously failing to implement commonsense security measures across the board, from using an insecure, consumer-grade Android smartphone to discussing nuclear strategy openly in a dining room at his Mar-a-Lago Club in Florida. Cybersecurity experts universally agree that an ordinary Android smartphone, which the President is reportedly using despite repeated warnings from the Secret Service, can be easily hacked.”

Both political and security experts are in agreement that the Samsung Galaxy S3 smartphone that Trump is using is not equipped to handle the kind of communication that a President is regularly expected to engage in. By continuing to use it, not only is he vulnerable to espionage, it could also lead to a spread in false intelligence.
