NBC News has put together a time-lapse video of the EF-4 tornado that tore through the southern suburbs of Oklahoma City, Okla.

As we told you in the live blog, the National Weather Service says it was at least an EF-4 tornado with winds in excess of 166 mph. The tornado stayed on the ground for 40 minutes and traveled 20 miles.

Although Oklahoma is a state where tornadoes are a fact of life, few days stand out like May 3, 1999.

It's another bad day for the Justice Department.

A federal judge in Louisiana has thrown out the central criminal charge against a former BP executive because prosecutors failed to prove he knew about a pending congressional investigation into oil flowing into the Gulf of Mexico three years ago. U.S. District Judge Kurt Engelhardt also ruled that a Democratic House member who inquired about the oil flow rate was acting as head of a subcommittee, not a full congressional committee, as required under the federal Obstruction of Justice statute.

Ray Manzarek, the keyboardist and a founding member of The Doors, died Monday in Germany. He was 74.

A statement from publicist Heidi Ellen Robinson-Fitzgerald said Manzarek died in Rosenheim, Germany, after a long battle with bile duct cancer.

Manzarek and Jim Morrison founded the iconic band after meeting in California. The Doors went on to become one of the most successful rock 'n' roll acts of the 1960s — and continues to have an impact decades after Morrison's death in 1971.

Microsoft hasn't exactly had a great couple of years.

Its new Windows 8 operating system was held responsible for the drop in PC sales last quarter. Sales of its Windows Phones lag far behind both the iPhone and Google's Android phones.

The light in the darkness for Microsoft has been the Xbox 360, which has been the top-selling game console for over two years — beating out both the Nintendo Wii and Sony's PlayStation. On Tuesday, Microsoft is expected to announce a new version of the Xbox.
