NASA Inspector General Robert Cobb submitted a letter of resignation to the White House on Thursday, April 2, 2009. President Barack Obama accepted Cobb's resignation, which is effective April 11.

The text of the letter is:

Dear Mr. President:

With this letter I tender my resignation as the Inspector General of the National Aeronautics and Space Administration, effective April 11, 2009.

I have been honored to serve the United States over the past seventeen years, first at the Office of Government Ethics, then at the White House, and for the last seven years as Inspector General.

A new Inspector General will find an organization with extraordinarily talented employees dedicated to rooting out fraud, waste, and abuse and promoting the economy, efficiency, and effectiveness of NASA.

At NASA, the seemingly impossible is turned into marvels of human achievement. Challenges facing NASA are many, but I am confident that they will be ably met by your Administration, working with NASA's gifted scientists, engineers, institutional leaders, and contractor workforce.

I wish you every success.

Very Respectfully,

Robert W. Cobb
