7 things to know now: Trump on abortion; tornadoes in Oklahoma; William Shatner sued

Here's a roundup of news trending across the nation and world today.

What to know now:

1. Trump on abortion: A remark by   Republican presidential front-runner Donald Trump drew swift and harsh criticism from every corner on Wednesday. Trump said during an interview with MSNBC’s Chris Matthews that women who end pregnancies should face punishment if the United States bans abortion. A few hours later, he stepped back his remarks, at first saying abortion is a state not federal issue then saying it is doctors who perform abortions who should be punished. "The doctor or any other person performing this illegal act upon a woman would be held legally responsible, not the woman," Trump said. "The woman is a victim in this case as is the life in her womb."

2. Aide resigns: The aide to Alabama Gov. Robert Bentley who has been at the center of rumors of an affair, resigned Wednesday. Rebekah Caldwell Mason issued a statement saying she would no longer be Bentley's senior political adviser nor be paid by his campaign fund. Also on Wednesday, an Alabama legislator announced plans to introduce a resolution to begin impeachment proceedings against the governor.

3. Don’t look for his name: Vermont Sen. Bernie Sanders' name will not appear on the Washington, D.C., primary ballot, after the Democratic Party failed to turn in Sanders' paperwork on time. Party officials admit they received paperwork and fees from both Sanders and Hillary Clinton's campaign, but only turned over Clinton's forms on time.

4. Not my son: Actor William Shatner is being sued for $170 million by a Florida man claiming to be his son. Peter Sloan, 59,  is asking for money and for Shatner to take a DNA test. Sloan says he is the product of an affair between his mother, actress Kathy McNeil, and Shatner. Sloan says Shatner, 85, admitted in 1984 on the set of "T.J. Hooker" that he was his father. Shatner denies he is Sloan’s father.

5. Officers won’t be charged: Two Minnesota police officers involved in the fatal shooting of a black man last year will not face charges, a prosecutor said Wednesday. Jamar Clark, 24, was shot and killed after he allegedly tried to get a gun from one of the officers. The prosecutor said the officers feared for their lives.
