Don't Expect to Hear From the White House Much Over the Next Week

President Joe Biden will remain out of town for an extended stay at Camp David as he and his campaign team work to ready the octogenarian commander-in-chief for next week's debate with former President Donald Trump. 

Already away from Washington at his home in Rehoboth Beach, Delaware, Biden will travel to the presidential retreat in Maryland on Thursday evening for a week-long stay at Camp David. A new FAA NOTAM (Notice to Airmen) confirmed the no-fly zone around Camp David until next Thursday, the date of Biden's showdown with Trump on CNN.

UPDATE: Great minds think alike.
