US President Barack Obama broke a Guinness record by becoming the fastest person to garner one million followers on Twitter, a feat he accomplished in less than five hours with his new account @POTUS, Efe news agency reported.


In obtaining a million followers in less than five hours, Obama broke the record previously set by actor Robert Downey Jr., who got to the one-million mark in 23 hours and 22 minutes in April 2014.


The president already has another Twitter account, @BarackObama, which is handled by the team that directed his second presidential campaign, Organizing for America, and the messages he has written there so far have been marked with the initials "bo" to differentiate them from tweets created by other presidential staffers.
