Former President Barack Obama was the first commander-in-chief to ever send a tweet, but President Donald Trump is pioneering an approach to mass communication that may put Twitter at the center of his strategy, raising legal and security questions.
In his first week on the job, Trump has used an unsecured Android phone to post tweets from his personal Twitter account, and to delete them. His staff initially used a personal email to arrange his government Twitter account, which was updated to a government email on Thursday.
@azalben: A bunch of folks have tweeted me about this (and thank you): @POTUS has added WH addresses to the Twitter account. Only 7 days late, guys!
Experts said these activities, while perfectly legal, create avoidable risks.
Using an unsecured phone, or personal email registration, makes the president more susceptible to hacking.
Some Members of Congress are now urging Trump to switch to a secure device, after the New York Times reported the president is tweeting from "his old, unsecured Android phone." The Secret Service has told past Presidents that they should only use a secure phone.

Even beyond cybersecurity, the ad-hoc approach suggests the Trump White House has not fully adjusted to the complexities of life in the federal government.
When Trump deleted a tweet, he likely violated the President Records Act, a 1978 law that requires all presidential writings be preserved. Congress recently amended it to include electronic records.
"If he uses his Twitter account for official presidential business, it should be subject to the Presidential Records Act," Caroline Mala Corbin, a constitutional law professor at the University Miami, said.
Congress passed the law "after the Watergate scandal and President Nixon's attempt to hide his records," she said, to establish that all presidential records "must be preserved."
