Here's Joe Sestak's statement on the McChrystal firing -- something he said was warranted in comments yesterday, while warning it might cause the US to miss a step in the fight in Afghanistan:

"Today, President Obama had to make a difficult decision - one that only the Commander in Chief can make. General McChrystal is a very able commander who has served our nation well. However, his conduct did not meet the standard befitting a commanding officer and threatened to undermine the civilian leadership that is the foundation of our nation's armed services. The mission is always more than any man or woman, and I believe the President made this decision based on the appropriate merits of what is best for our efforts in Afghanistan/Pakistan for the security of the United States.  There is no one more capable to lead the effort in Afghanistan than General David Petraeus. General Petraeus, our troops in the field, and our military families here at home should be confident in the full support of their civilian leadership, military commanders, and a grateful nation."
