The Latest on the 2016 presidential campaign a day before the Republican presidential debate and ahead of Saturday's Democratic presidential primary in South Carolina : Marco Rubio has attacked Donald Trump by name, criticizing the candidate he called the GOP front-runner for not strongly opposing the federal health care law and for suggesting he could be a moderator in the Israeli Palestinian conflict.
At a Houston rally, the Florida senator said "the front-runner in this race, Donald Trump, has said he's not going to take sides on Israel versus the Palestinians because he wants to be an honest broker."
Ted Cruz is pledging to order a federal investigation of Planned Parenthood if elected president and says undercover videos appear to show the health provider is "a national criminal enterprise."
Activists secretly recorded videos they allege show that Planned Parenthood sold fetal tissue to researchers for a profit in violation of federal law.
