WaPo Correction of the Week: When 911 Really is a Joke
Incident on Potomac River Was Just an Exercise
CNN originally reported that the U.S. Coast Guard had opened fire on a boat in the Potomac River this morning, but the incident was actually a training exercise. Given the exercise's timing and location, on the morning of September 11, near the Pentagon, at a time when President Obama was laying a wreath to honor the victims of 9/11, the incident initially caused panic across the area.
Sign Up for 9/11 National Day of Service
President Barack Obama has declared that September, 11, 2009, the eighth anniversary of the 9/11 terrorist attacks, will mark the first 9/11 National Day of Service, and Greater DC Cares has responded by organizing a large number of volunteer and service opportunities for Washington area residents. Individuals and teams may both sign up online to serve on projects ranging from spending time with seniors to cleaning up Hains Point to preparing meals for the chronically ill. A $25 per person registration fee covers the costs of the event in addition to helping fund Greater DC Cares all year. Registration is open now through Tuesday, September 8.
