We are live on the ground in Ferguson, Missouri, with the latest news and analysis.
The Guardian newspaper revealed the identity of the National Security Agency leaker behind recent revelations of NSA surveillance.
Edward Snowden is a 29-year-old intelligence contractor, who revealed the extent to which the government is monitoring and keeping records of not just telephone calls, but also e-mails, internet searches, downloads and photos.
Snowden has been in Hong Kong staying in a hotel room since late May, according to The Guardian. There are reports that since his identity was revealed on Saturday, he has checked out of his Hong Kong hotel.
The Guardian's Glenn Greenwald tells CNN's Jake Tapper that he knows where Snowden is, but will not disclose the specific location of his source.

As news of Snowden's involvement became known, supporters have expressed concern that he does not have enough money, and that his hotel bills are piling up.
Greenwald said The Guardian newspaper is not helping Snowden pay for his room or meals, and said Snowden is using personal savings to pay for his hotel and living expenses.
"Since he came out ... 24 hours ago, there's been this amazing outpouring around the world of people who are expressing all kinds of gratitude and admiration for what he did to inform the world about the U.S. surveillance state, who have offered all kinds of funds. And I know there are people who are starting legal defense funds and other forms of funds to help him," said Greenwald.
"So I think on Edward Snowden's long list of worries, money is probably very low on the list, if it's on the list at all," said Greenwald.
