question:
Washington (CNN) If Donald Trump's campaign aides like Paul Manafort were contacting Russian officials during the campaign, then the President had nothing to do with it, claims former Trump campaign manager Corey Lewandowski. "If anybody crossed a line and gave information to a foreign agent or foreign government or foreign intelligence official, whether that's Paul Manafort or it's Rick Gates or anybody else, I hope they're held accountable," Lewandowski told David Axelrod on "The Axe Files," a podcast from the University of Chicago Institute of Politics and CNN. He later added: "Any staffer who contacted or potentially contacted a Russian agent or a Russian official has done so on their own accord and not at the direction of the campaign, the President or anybody else in the administration."Lewandowski attempted to shield the PresidentManafort has denied the alleged contact as "100% not true" 
 Question:Lewandowski and _ were considered part of two rival power centers in the campaign during the time they overlapped.

question:
A British national held hostage in Yemen has been freed in a 'military intelligence' operation, according to Foreign Secretary Philip Hammond. The Briton, who has been identified as Robert Douglas Semple, 64, was released by United Arab Emirates forces. The freed hostage had been working as a petroleum engineer in the Yemeni province of Hadramawt when he was kidnapped in February 2014. The UAE forces were based in Yemen's main port city of Aden, according to the state news agency WAM. The Yemeni agency reported that he had been held by al-Qaeda for 18 months.

question:
(CNN) The family of an African-American man fatally shot in the back by Chicago police last week filed a federal civil rights lawsuit against the officers alleging wrongful death and excessive force. The lawsuit, filed Monday, alleges the police officers fired at Paul O'Neal "without lawful justification or excuse." It's the latest shooting to highlight the already tenuous relationship between some communities and police, and it touches on broader issues that have time and again racked the Windy City: body cameras, police accountability and seemingly unstemmable violence. Many in the nation's third-largest city are still reeling from the 2014 Laquan McDonald shooting, which left a Chicago officer facing a murder charge after more than a yearlong delay in releasing dashboard camera footage. And earlier this year, a task force established by the mayor released a report accusing the police of widespread racism.Police Superintendent Eddie Johnson relieves three officers of police powersPolice investigate how suspected car thief was shot in back; body cam didn't record
