The White House announced that President Obama will deliver a speech today at 1 p.m. ET.
The AP reports that Obama will likely address the first downgrade of the country's credit rating in history. And the president is also expected to talk about the 30 U.S. troops killed in a helicopter crash in Afghanistan on Saturday.
You can listen to the president live on NPR.org and CSpan will stream video of it. We will live blog it here, too.
