Via the Washington Post:

American diplomats concerned they’re being replaced by NASA employees, breathe easy: The Space agency and its administrator, Charles Bolden, are not responsible for reaching out to the Muslim world after all.
Bolden caused a global stir last week when he said President Obama had asked him to reach out to Muslim leaders on science issues. He made the comments during an interview with Al Jazeera while visiting Egypt.
But White House press secretary Robert Gibbs said Monday, “That was not his task, and that’s not the task of NASA.”
Gibbs said White House officials have spoken to Bolden and NASA about the comments.
