"All Things Considered" host Ari Shapiro is leaving NPR.

The NPR journalist said in an Aug. 20 statement that as he enters "the next chapter of my own professional evolution, I can't imagine an organization more uniquely prepared to deliver the kind of illumination, understanding, and joy that I have treasured my entire life — and will continue to depend on as a listener."

Shapiro, 46, joined NPR as an intern for NPR legal affairs correspondent Nina Totenberg in 2001, spending the last 10 years as one of the hosts of "ATC." He has served as an international correspondent, a White House correspondent and a justice correspondent.

"This has been the second-longest relationship of my adult life (after my marriage), and I am both deeply grateful and exceptionally proud to have become the journalist — and the person — I am because of NPR," Shapiro added.
