[Q]: (CNN) -- The Circuit of the Americas in Austin, Texas lies just 200 miles from the Mexican border. On Sunday it will host the first U.S. Grand Prix since 2007 -- and thousands of Formula One fans are expected to cross the Rio Grande to cheer on a driver they know as "Checo." Sergio Perez has become one of the darlings of Mexico, a country that in recent times has become more synonymous for the drugs war waged by Felipe Calderon during his tenure as president. The sporting focus this weekend will be on America, but the problems of its neighbor will come into sharp focus in the Mexican town of Nuevo Laredo -- the closest crossing point for those hoping to see Perez at what is, in effect, his home race.Formula One driver Sergio Perez looking forward to his "home" race in Texas on SundayThe Mexican is expected to have thousands of fans crossing the border to support himHe has been one of F1's surprise success stories in only his second season on the gridPerez has earned a big-money move to McLaren after three podium placings in 2012

[Q]: (CNN) The Marine Corps' fighting ability is undermined by the more than 30,000 active Marines and veterans involved in a private Facebook group being investigated for allegedly posting explicit photos of women in the military without their consent, a former Navy secretary told CNN on Friday. "There's no good excuse," Ray Mabus said on CNN's New Day. "The Marine motto is 'semper fidelis,' always faithful, and what these Marines did was to be unfaithful to their fellow Marines." "Marines look after each other, Marines have each other's back. Look at what the commandant of the Marine Corps said about this, this makes us a less effective fighting force," Mabus said, referring to a video statement posted Tuesday by Gen. Robert Neller.Ray Mabus: "What these Marines did was to be unfaithful to their fellow Marines"Investigation should determine how "Marines United" group developed, he said 
 Question:"These Marines, these veterans, that have participated in this have attacked fellow _, and that is inexcusable in a fighting force, and particularly in the Marines, who are so special."

[Q]: On a day when Chris Froome has never been under greater scrutiny, when everything from his heart rate to his power output is being used as evidence against him, he responded by delivering a performance so astonishing he might just have this Tour de France won after 10 days.
