An investigator said Monday that the commuter train that derailed Sunday in New York was going too fast as it entered a curve. Though the train was traveling at 82 miles per hour while rounding a 30 mph curve, it was not clear whether that was because of human error or a problem with the brakes. Officials also did not know why the brakes were only fully engaged five seconds before the train stopped, and it takes a train a mile to stop while going 70 mph. Read full story here.

The rebooted HealthCare.gov website served 375,000 customers by noon Monday, government officials said, but the site faces another test in a few weeks.

The military has said the draft is a step toward democracy and would prove its credibility in a post-Morsi system.
