Late Update: Blair confirms his resignation with this statement.
It is with deep regret that I informed the President today that I will step down as Director of National Intelligence effective Friday, May 28th.
I have had no greater honor or pleasure than to lead the remarkably talented and patriotic men and women of the Intelligence Community.
Every day, you have worked tirelessly to provide intelligence support for two wars and to prevent an attack on our homeland.
You are true heroes, just like the members of the Armed Forces, firefighters, and police whose job it is to keep our nation safe.
Your work over the past 16 months has made the Intelligence Community more integrated, agile, and representative of American values. Keep it up - I will be cheering for you.
Dennis C. Blair
Later Update: President Obama releases a statement of his own.
Dennis Blair has a remarkable record of service to the United States, and I am grateful for his leadership as Director of National Intelligence. Over the course of many decades, Admiral Blair has served with great integrity, intellect, and commitment to our country and the values that we hold dear. During his time as DNI, our intelligence community has performed admirably and effectively at a time of great challenges to our security, and I have valued his sense of purpose and patriotism. He and I both share a deep admiration for the men and women of our intelligence community, who are performing extraordinary and indispensable service to our nation.
