President Obama became the first sitting president to appear on late-night when he visited The Tonight Show With Jay Leno in March 2009. Now he is set to return to the NBC show August 6 — it will be his sixth appearance, the most recent one coming in October. That pre-election visit resulted in a big ratings boost for the now departing Leno. According to White House Press Secretary Jay Carney today, the President will be giving an economic policy speech near Phoenix earlier on the day of the 6th before taping with Leno in Burbank. While details on the rest of Obama’s schedule are sketchy, he will be staying in the area after his Tonight Show appearance. Obama is set to head to Camp Pendleton on the 7th for a visit with the Marines based there.
