WASHINGTON - President Barack Obama on Sunday encouraged parents to vaccinate their children and said the U.S. is doing everything in its power to rescue a 26-year-old woman held by the Islamic State, speaking in a wide-ranging interview also covering football and politics.Obamas comments to NBC came as the U.S. grapples with a measles outbreak traced back to Californias Disneyland theme park and a day after a Japanese journalist held by the militants was purportedly beheaded.Obama says he has watched videos of hostages being beheaded. Every morning I get a presidential daily briefing and it gives me a pretty clear sense of the terrible stuff thats happening. And its part of the reason why we have to be so vigilant and so aggressive in going after a vicious organization like ISIL, Obama said, using an acronym for the Islamic State group.Three Americans — aid worker Peter Kassig and journalists James Foley and Steven Sotloff — were beheaded last year by the Islamic State. A fourth American being held is a woman captured last year in Syria while working for aid groups. U.S. officials have asked that she not be identified out of fears for her safety.Obviously this is something that is heart-breaking for the family and we want to make sure we do anything we can to make sure that any American citizen is rescued from this situation, Obama said.On the measles outbreak that has spread to more than 100 people, Obama said children who are not vaccinated are putting infants and other people who cant get vaccinations at risk. You should get your kids vaccinated, Obama said directly.Some parents continue to believe debunked research linking vaccines to autism and refuse to vaccinate their children.I understand that there are families that, in some cases, are concerned about the effect of vaccinations, Obama said. The science is, you know, pretty indisputable.Obama spoke to NBCs Savannah Guthrie before hosting a Super Bowl party at the White House for his friends. His comments on terrorism and vaccinations were taped to air on The Today Show Monday, but NBC released excerpts in advance.Lighter topics were covered in a short segment that aired live in the pregame show. As Guthrie and Obama sampled White House-brewed beer from the executive mansions kitchen, they mixed a discussion of the games high-profile controversy — deflated footballs — with a brief discussion of politics.But the president ducked picking between possible 2016 Democratic presidential contenders Joe Biden and Hillary Rodham Clinton. Love em both, Obama said with a smile.He also wouldnt pick a favourite in the New England Patriots Super Bowl match-up against the Seattle Seahawks. I think its always wise for me not to choose a team because then I just alienate one big city, Obama said.As the NFL investigates how the Patriots used the deflated balls in their 45-7 AFC championship victory, Obama said the team would have defeated the Indianapolis Colts regardless of what the footballs looked like.The one thing I did not realize — and Ill bet most fans didnt — was that each team prepares its own footballs and brings them to the game, Obama said. I dont think theres any other sport like that so Im assuming one of the things the NFL is going to be doing just to avoid any of these controversies is figuring out how the officials are in charge of the footballs from start to finish.Pressed on whether the Patriots were cheating, Obama said: I think that if you break the rules then you break the rules.The president rejected the idea he was doing his own end zone dance with a defiant State of the Union address after Democrats lost seats in the midterm election. My job is not to trim my sails, Obama said, confidently arguing for his ability to win over even some of his political rivals. He spoke on the eve of his presentation of a budget to Congress, where his proposals are certain to get a rough reception from the Republican majority.One thing Ive learned over the last six years is that when I tell the American people very clearly what direction I think the country should go in, sometimes people change their minds, Obama said. And even Republicans occasionally start agreeing with me, although sometimes a little bit later than I would like.___Follow Nedra Pickler on Twitter at https://twitter.com/nedrapicklerSan Antonio Spurs Jerseys .

Dejounte Murray Spurs Jersey .Y. -- Phil Jackson lost out on his preferred coach, but hes working hard on keeping his star player.SCOTTSDALE, Ariz. -- Challenged for the first time under Major League Baseballs expanded replay system, umpires got it right. The umps went 3 for 3 on Monday as MLB tried out the new format at three spring training games. The first test came at 3:06 p.m. EST in Fort Myers, Fla., after first base umpire Fieldin Culbreth ruled Toronto shortstop Munenori Kawasakis throw pulled Jared Goedert off the bag in the sixth inning. "Im not too sure that youre not right here," Culbreth said Blue Jays manager John Gibbons told him, "but since we havent done it before, lets go take a look." Culbreth answered: "OK. Thats what its for." After 2 minutes, 34 seconds, replay umpire Brian ONora relayed his call by headset, confirming that Minnesota batter Chris Rahl was safe. During the wait, Rahl said he realized he perhaps was part of history. "Its kind of funny. I was thinking, Is this the first one?" he said. ONora made the final ruling from a satellite truck outside the stadium. During the regular season, umpires on the field will check with the replay booth in New York, where an MLB umpire will make the final call. Later in the game, Culbreth rotated and took a turn in the truck, confirming another safe call at first base. "Im looking at this thing as, this is the future of the game. And Im going to treat these games here the same way that Im going to treat them during the regular season," Culbreth said. In the eighth inning, Doug Bernier of the Twins was called safe on a close play at first. As Culbreth studied the replay, the ballpark sound system played a Rolling Stones song with the familiar lyric, "I cant get no satisfaction." The call was confirmed, Bernier was safe. Extra replay also was in place for two games in Arizona -- the Los Angeles Angels vs. Arizona Diamondbacks in Scottsdale and the Chicago Cubs against Milwaukee in Phoenix. Each team in the majors will have at least five exhibition games with the new system in place. In January, owners approved the use of additional video replay to review most calls other than balls-and-strikes. Previously, umpires could only go to replay to review home runs and boundary calls. Moments after the first replay call, Angels manager Mike Scioscia wasted little time in using his challenge. In the top of the second, Luis Jimenez of the Angels tried to steal second. Catcher Bobby Wilsons throw was high but second base umpire Bill Miller ruleed that Aaron Hill tagged the runner out.dddddddddddd Scioscia bounded out of the dugout and charged toward Miller to argue, just like managers always have done. Instead, though, he chose to use his challenge. After two of the umpires made a quick visit to the Angels dugout to communicate with the replay umpire, the call was upheld. "We werent trying to make a mockery out of it," Scioscia said of using the challenge so soon. "We thought it was a pretty close play." There was only one angle available with the limited camera work of a spring training telecast. "If we have 15 angles of that," Scioscia said, "theres a possibility it gets reversed." That review took 2:31. Since he lost the challenge, Scioscia had no more. "I dont think its going to take much time in the logistics. That will smooth out," he said. "As far as the strategy of it, thats going to take a lot. It might be something you win, but you know you need that challenge to save the big play somewhere." Twins manager Ron Gardenhire and Arizonas Kirk Gibson did not use their challenge. Neither did Cubs manager Rick Renteria nor the Brewers Ron Roenicke. Gibson said he thought about contesting a close play when Paul Goldschmidt nearly beat out a grounder but said he decided it was 50-50 and not worth it. "I think its going to be a lot more complicated than we thought," Gibson said. "We had a lot of conversation during the game." For the Angels-Diamondbacks game, the replay trailer was set up in the parking lot behind centre field. Teams are allowed to have a person to watch the game on television and advise the managers via phone whether it would be worth it for the call to be challenged. The Angels communicated via walkie talkie Monday but there will be a dedicated phone line for each team in the major league parks. Under the new rules, each manager has one challenge. If the first challenge is successful, the manager gets a second. From the seventh inning on, if the manager is out of challenges, the umpire can decide to have the play reviewed. Some critics of expanded replay worried that challenges would delay the game too much. Culbreth said he didnt think that would be a problem, and pointed at the benefits. "It will work itself out. I think time really isnt going to be an issue in the end," he said. "And if it is, its about getting the play right in the end, anyhow." ' ' '
