US President Barack Obama is slated to hold a "Twitter town hall" meeting on 6 July.

Obama would take questions exclusively from Twitter to answer question on jobs, economy and war, which the president will answer verbally on a live webcast.

The event was announced by the White House. It has solicited questions on the micro-blogging site under the hash tag #AskObama.

Twitter co-founder Jack Dorsey will be moderating the event.

Twitter has also made it into the headlines for two more events in the recent past.

First, officials of the North Atlantic Treaty Organisation (NATO) used the micro-blogging site to gather information from users, such as geolocation, to identify air strike targets in Libya.

And second, Obama selected Twitter’s chief Dick Costolo to join his National Security Telecommunications Advisory Committee.

Meanwhile, the Federal Trade Commission antitrust investigators are reportedly investigating the way Twitter deals with third party companies which supply it applications and services.

Twitter has not commented on the matter so far

Obama started using social media since 2007, when he used it in his campaign for the presidency.

In April this year, Obama launched his 2012 re-election campaign with social media as well with an exclusive website, and Twitter and Facebook accounts.

Then, Obama told the 7.28 million followers of the @barackobama account on Twitter, "Today, we’re filing papers to launch our 2012 campaign."

"We’re doing this now because the politics we believe in does not start with expensive TV ads or extravaganzas, but with you — with people organising block-by-block, talking to neighbours, co-workers, and friends. And that kind of campaign takes time to build."

Obama hopes to use social media to start big discussions.

He had written on the website, "We’ll start by doing something unprecedented: coordinating millions of one-on-one conversations between supporters across every single state, reconnecting old friends, inspiring new ones to join the cause, and readying ourselves for next year’s fight."
