[Q]: A nurse's release Tuesday from an Atlanta hospital leaves a single person in the United States now battling Ebola, though she and others -- including President Barack Obama -- stressed the fight against the deadly virus isn't over. "While this is a day for celebration and gratitude, I ask that we not lose focus on the thousands of families who continue to labor under the burden of this disease in West Africa," said 29-year-old Amber Vinson. About two weeks ago, Vinson became the second nurse from Texas Health Presbyterian Hospital Dallas to get the virus while caring for Thomas Eric Duncan, a Liberian man who began showing Ebola symptoms after arriving in Texas and died of it there. She and Nina Pham -- the other Dallas nurse who was discharged from a National Institutes of Health facility in Maryland on Friday -- are differ from the handful of other U.S. Ebola cases in the United States because they caught the disease in America, rather than contracting it in West Africa.Discharged nurse asks that we don't "lose focus" on those suffering in West AfricaU.S. cannot "react based on our fears," President Obama saysU.S. diplomat arrives in Liberia to show "solidarity"There's now only one person, a doctor in New York, with Ebola in the United States 
 Question:Even without more cases, _ remains a hot topic of conversation around the country.

[Q]: (CNN) Though many individuals likely contributed to the President's decision to fire FBI Director James Comey, one notable one may have been Roger Stone, a 64-year-old close friend of Donald Trump and central figure in the FBI investigation into Trump campaign ties to Russia. In the middle of the Watergate scandal, Stone, who engaged in dirty tricks during Richard Nixon's 1972 campaign, was discovered to have hired a Republican operative to infiltrate the George McGovern campaign and was subsequently fired from his job. After the President's resignation, Stone remained an ardent Nixon apologist and loyalist. He even had the man's face tattooed on his back and devoted his life to ruthless, anything-goes politics (or political consulting, as you may know it). Stone's motto was and continues to be: "Admit nothing, deny everything, launch counterattack." And anyone who has watched Trump closely over the years would think it was his personal slogan, too.Michael D'Antonio: Roger Stone has undoubtedly influenced President Trump's decision to fire James ComeyAs an old friend and political adviser, Stone has taught Trump be ruthless -- particularly when protecting himself from attackTherefore Comey, who was leading the investigation into Trump campaign ties to Russia, had to be taken out, writes D'Antonio 
 Question:Then, in the spring of 2016, _ seemed to embrace him again.
[A]: Donald Trump


[Q]: (CNN) The Republican Party's efforts to gut former President Barack Obama's legacy health care law came to an abrupt -- if temporary -- halt Monday night. Just hours after the Senate was gaveled back into session, Senate Majority Leader Mitch McConnell was handed two more public defections on his health care bill to overhaul Obamacare. The dramatic and simultaneous announcement from Sens. Jerry Moran of Kansas and Mike Lee of Utah means McConnell officially does not have the votes to even begin debate on his legislation to overhaul the Affordable Care Act. The development deals a devastating blow not only to Republicans who have railed against the law for years, but also President Donald Trump, who campaigned on killing Obamacare and made repealing the law his top legislative priority since taking office.Mitch McConnell could only afford to lose two senators and still advance the legislationOn Monday night, Sens. Mike Lee and Jerry Moran became no votes three and four
