As you may already have heard, there was a shooting outside the White House a short time ago. President Obama was not at the White House at the time. It is still a developing situation and we are monitoring all media reports and we have our own reporter on the scene filing reports. Watch this post for updates as well as Livewire for more details as they become available.
