The United States military is getting more involved in the Haiti relief effort by the day. On Wednesday, 4,000 more troops were added, bringing the total U.S. presence in the country to about 16,000. As the chairman of the Joint Chiefs of Staff, Adm. Mike Mullen is the country's highest ranking officer in the armed services. John sat down with Adm. Mullen at the Pentagon on Wednesday for a wide-ranging conversation. In part one of our interview, we ask him about the use of Guantanamo Bay in the relief effort, the "war" with Al Qaeda, and the renewed focus on Yemen.

Alex here shepherding tomorrow's show through the night ... 

As already posted on this website, John Hockenberry interviewed the Chairman of the Joint Chiefs of Staff, Admiral Michael Mullen today. We'll run that tomorrow along with our continuing coverage of the political fallout from the electoral upset in Massachusetts. Democratic Congressman Anthony Weiner (NY) will tell us why the Dems are OK without a filibuster proof majority in the Senate. 

We might have heavy hitters from Washington (or right outside Washington in the Pentagon anyway) but we're not letting up on watching the relief efforts in Haiti. After a serious aftershock today a friend of the show wrote us to say "the aftershock was stronger than I realized and we are concerned more buildings have collapsed. People are screaming outside." So tomorrow we'll get the full update live. We're also following a few different 'big picture' angles. For one, we want to know if the medical risks to patients and doctors are evolving or growing over time with so many victims remaining injured and bodies still unburied. And on a political level, three prominent female political leaders were victims of the quake, so we're looking into what that means for gender progress in Haitian politics. 

Plus graphic journalist Joe Sacco, how Starbucks bounced back, and an examination of the Apple buzz-making machine. 

See ya tomorrow.
