US President Barack Obama has sent his first tweet from his very own account on Twitter, quickly amassing a million followers in five hours, the latest of many White House efforts to amplify his message with social media.
"Hello, Twitter! It's Barack. Really! Six years in, they're finally giving me my own account," Obama tweeted from his verified @POTUS account.
A Twitter spokesman could not immediately confirm whether Obama had set a record. According to Guinness World Records, the fastest pace to a million followers was set by actor Robert Downey Jr in 23 hours and 22 minutes in April 2014.
Obama and his advisers pioneered the use of social media in the 2008 presidential campaign and have embraced their use in the White House as well.
As media attention has increasing shifted toward the 2016 presidential campaign, the White House has boosted its use of social media to break and shape news.
Today, the White House tweeted a short video of Obama sending his tweet from the Oval Office, using a White House iPhone .
