Before IBM's Watson and Deep Blue, there was another celebrity robot: Elektro.

The first robot introduced to Americans, Elektro was the 7-foot-tall man who greeted millions of visitors who streamed through the gates of the 1939 World's Fair. He even appeared on film, in The Middleton Family at the New York World's Fair.

The robot was built as a showpiece for the manufacturer Westinghouse, which made clothing irons and ovens in Mansfield, Ohio, at the time.

The attorney of the man accused of shooting 17-year-old Trayvon Martin says "this is not a race issue."

During an interview with Tell Me More's Michel Martin (no relation), attorney Craig Sonner said his client George Zimmerman had black friends, who he's talked to and they have vouched for him.

In his 1995 autobiography, Under a Hoodoo Moon, Dr. John writes about his tumultuous music career, a decades-long heroin addiction and the time he spent in prison on a drug-possession charge. The book is candid in a way that most of his music is not — until now. On his new album, Locked Down, Dr. John takes a more personal approach.

Here's some good news about Americans' diets: Most of us are getting sufficient amounts of key vitamins and minerals. That's the finding of a nutrition report just out from the Centers for Disease Control and Prevention's National Center for Health Statistics.

Vitamins A and D, folate, iron and iodine are just a few of the nutrients assessed in the nationwide survey, which uses data collected between 1999 and 2006. Overall, less than 10 percent of the population appeared deficient in each nutrient.

A gunman opened fire inside a Christian university in Oakland. Several people were shot and multiple people were dead at the Oikos University campus.

The Oakland Police Department tweeted that a "possible suspect" was in custody so there was "no imminent public safety threat."

Update at 9:19 p.m. Police Identify Suspect:

Reporting that it has had the video "clarified" by a forensics company, ABC News is now saying that a police surveillance recording of George Zimmerman "shows the neighborhood watch captain with an injury to the back of his head."
