IIRC, shortly after this story came out, it was discovered that the tweet was from an official account, but was made by a former employee that still had the password to the twitter account.
Tells you about the writer adding more to the growing view that today’s journalism is sloppy, lazy, and politically motivated.
Before writing, data need to be checked as factual, unless one doesn’t care about facts but is more interested in a politicized narrative.
If the writer had dug deeper, his headline would read “Former Obama employee illegally posts official tweet”. The story could then add detail that the former employee is former because dadada, and is anti-Trump (if found), and was known to rant about President Trump (if found), and was able to tweet in defiance of the President’s orders to go silent on social media, and was able to tweet because he/she had a previous twitter account with a password that was still good, etc.
The research could then go in the direction of contacting the PR Officer if not the former employee’s supervisor to ask if they were aware that this former employee was able to tweet on an official twitter account and hear their story, then ask what is being done about it, etc.
That would be a story. But we see little of that basic kind of research and reporting today.
