If jurors in a federal trial in Florida believe government prosecutors, the wife of the man who carried out one of the U.S.'s biggest mass shootings gave a "green light" to her husband when he wanted to execute his terrorist-inspired attack.
But if they accept Noor Salman's attorney's account that she was a "devoted mother" with an IQ of 84 and was the victim of Omar Mateen's repeated lies throughout their marriage, they could decide she had no prior knowledge of the attack.
Salman went on trial Wednesday in Orlando. The 31-year-old is accused of aiding and abetting her husband in his attack on the Pulse nightclub in June of 2016. She's also charged with obstruction of justice. If convicted, she faces life in prison.

President Donald Trump fired Secretary of State Rex Tillerson on Tuesday, bringing Tillerson's rocky tenure to an abrupt end after months of disagreements. Trump tapped CIA Director Mike Pompeo to replace Tillerson and is elevating Deputy CIA Director Gina Haspel to become the first woman to lead the spy agency.
Tillerson, the former chief executive of Exxon Mobil, was not consulted about the president's decision, according to an undersecretary of state. His relationship with Trump had soured over a period of months, and he learned he had been fired from a tweet, senior State Department officials told NBC News.

Walmart is expanding its same-day online grocery delivery service to more than 40 percent of U.S. households, or 100 metro areas, by year-end as it tries to keep pace with online leader Amazon.com.

So far, Walmart offers curbside grocery pickup at 1,200 stores and plans to accelerate the rollout to 2,200 by year-end. It's currently using 18,000 personal shoppers.

Three package bombs left on doorsteps in suburban Austin neighborhoods have killed two people and wounded two others in under two weeks in Texas' capital city, leaving investigators searching for any possible motive.
Police said the bombings in east Austin — two on Monday and one on March 2 — are likely linked. Investigators are looking into whether race was a factor, police said, because all the victims have been minorities. However, they backed off initial suggestions that hate crimes could be a core cause and are not ruling out any possibilities.
President Donald Trump tweeted a study that says the proposed $18 billion border wall between the United States and Mexico will pay for itself. Others have refuted that report.
