Sanders Demands Clinton Apologize, Trump Clarifies Abortion Stance, Possible Contested GOP Convention

Donald Trump on Friday appeared to again reverse his position on abortion, arguing that federal laws should not be changed to outlaw the procedure. "At this moment the laws are set. And I think we have to leave it that way," Trump said Friday in an interview with CBS's John Dickerson on "Face the Nation." The full interview will air Sunday morning. But soon after the comments became public, Trump campaign spokeswoman Hope Hicks said Trump was giving "an accurate account of the law as it is today and made clear it must stay that way now -- until he is president. Then he will change the law through his judicial appointments and allow the states to protect the unborn. There is nothing new or different here." President Barack Obama said Donald Trump's suggestion that Japan and South Korea should consider obtaining nuclear weapons demonstrates the Republican presidential front-runner's lack of understanding about foreign policy and the world at large. "The person who made the statements doesn't know much about foreign policy or nuclear policy or the Korean Peninsula or the world generally," Obama said at a news conference at the close of the Nuclear Security Summit. Obama described the U.S. nuclear umbrella for Japan and South Korea, in place of their own arsenals, as "one of the cornerstones of our presence in the Asia Pacific," which has provided the U.S. peace, prosperity and flowing commerce. "It has prevented the possibilities of a nuclear escalation and conflict," he added. "You don't mess with that. It's an investment that rests on the sacrifices that our men and women made" in World War II. In an unusually direct move, Sen. Bernie Sanders on Friday called on Hillary Clinton to apologize to him for saying that his campaign is lying about her relationship with fossil fuel money. "Secretary Clinton owes us an apology. We were not lying. We were telling the truth," the Vermont senator said during a standard section of his stump speech here. Sanders was referring to a video released Thursday that shows Clinton angrily responding to an activist affiliated with Greenpeace and 350 Action, two climate organizations, who asked Clinton if she will "reject fossil fuel money" from her campaign. "I do not have, I have money from people who work for fossil fuel companies," Clinton said. "I'm so sick. I'm so sick of the Sanders' campaign lying about me. I'm sick of it." Donald Trump is again declining to rule out launching an independent bid for the White House, a decision that Trump says he has not yet made but one that could scramble the November election. "I want to run as a Republican. I will beat Hillary Clinton," he told Fox's Chris Wallace in an interview set to air Sunday morning on "Fox News Sunday." Excerpts of the interview were released Friday night. But when pressed to definitively say he would not consider it, Trump added, "I'm gonna have to see how I was treated. It's very simple."
