Problem: Background: Peter Gregg Arnett, ONZM (born 13 November 1934) is a New Zealand-born journalist holding both New Zealand and US citizenship. Arnett worked for National Geographic magazine, and later for various television networks, most notably CNN. He is known for his coverage of the Vietnam War and the Gulf War. He was awarded the 1966 Pulitzer Prize in International Reporting for his work in Vietnam from 1962 to 1975, mostly reporting for the Associated Press.
Context: Arnett worked for CNN for 18 years ending in 1999. During the Gulf War, he became a household name worldwide when he became the only reporter with live coverage directly from Baghdad. His dramatic reports often had air raid sirens blaring and the sound of US bombs exploding in the background. Together with two other CNN journalists, Bernard Shaw and John Holliman, Arnett brought continuous coverage from Baghdad for the 16 initial intense hours of the war (17 January 1991). Although 40 foreign journalists were present at the Al-Rashid Hotel in Baghdad at the time, only CNN possessed the means -- a private phone line connected to neighboring Amman, Jordan -- to communicate to the outside world. CNN broadcast Arnett's extended call live for several hours, with a picture of Arnett as video. Soon the other journalists left Iraq, including the two CNN colleagues, which left Arnett as the sole remaining reporter.  His accounts of civilian damage caused by the bombing were not well received by the coalition war administration, who by their constant use of terms like "smart bombs" and "surgical precision" in their public statements, had tried to project an image that civilian casualties would be at a minimum. White House sources would later state that Arnett was being used as a tool for Iraqi disinformation, and CNN received a letter from 34 members of the United States Congress accusing Arnett of "unpatriotic journalism".  Two weeks into the war, Arnett was able to obtain an exclusive, uncensored interview with Saddam Hussein. The Gulf War became the first war to be seen truly live on TV, due to Arnett's reporting from the "other side", for a period of five weeks.  About halfway through the war the CIA approached Mr. Arnett. They believed that the Iraqi military was operating a high-level communication network from the basement of the Al Rashid Hotel, which is where Mr. Arnett and a few others from CNN were staying. The CIA wanted him out so the Air Force could bomb the hotel, but Mr. Arnett refused. He said he had been given a tour of the hotel and denied there was such a facility.
Question: anything else important or notable?
Answer: The CIA wanted him out so the Air Force could bomb the hotel, but Mr. Arnett refused.

Problem: Background: Rex Ryan and his fraternal twin, Rob, were born in Ardmore, Oklahoma, on December 13, 1962, to Doris and Buddy Ryan. When the boys were aged two, their parents amicably divorced. Following the divorce, their mother attended the University of Chicago to earn her doctorate. Rex, Rob, and their older brother Jim moved with her to Toronto, Ontario, Canada, where she secured an administrative position at the University of Toronto.
Context: Ryan is an avid hockey fan and has developed a notoriety of being a bandwagon jumper in recent years. Ryan has admitted he was a fan of the Toronto Maple Leafs, as a result of growing up in the city, but upon taking the Jets head coaching job, he was often seen cheering for all three of the New York metropolitan area franchises. During the New Jersey Devils run to the 2012 Stanley Cup Finals, Ryan was seen sporting the team's attire, and he was seen donning the attire of the New York Rangers two years later, during their run to the Stanley Cup Final. Outside of the playoff runs, Ryan performed a ceremonial puck drop at Nassau Veterans Memorial Coliseum on October 9, 2010, wearing a vintage New York Islanders Billy Smith jersey.  Ryan was known for a notorious incident at a Carolina Hurricanes game, as he attended the matchup with the Florida Panthers sporting a throwback Philadelphia Flyers jersey on. Upon being recognized by the fans at the arena, the team's cheerleaders approached him with a Hurricanes alternate jersey sported by the team. The incident was noted as he was seen taking off the jersey and baring his chest for the crowd to see.  Upon taking the Buffalo Bills head coaching job, Ryan changed his allegiance to the Buffalo Sabres, and he was often seen at the team's home games and sporting the team's attire. Months after being fired by the Bills, Ryan would later be seen during the Nashville Predators run to the 2017 Stanley Cup Final, wearing the team's jersey.

Problem: Background: Angle was born in the Pittsburgh suburb of Mt. Lebanon Township, Pennsylvania, the son of Jackie and David Angle. He attended Clarion University of Pennsylvania, graduating with a degree in education in 1993. Angle has four older brothers (one of whom, Eric, is also a wrestler) and a sister, Le'Anne, who died in 2003. His father, a crane operator, was killed in a construction accident when Angle was 16, and Angle dedicated both his career and his autobiography to his father.
Context: Angle was arrested at his home by police in Moon, Pennsylvania on September 28, 2007, on a charge of driving under the influence after being reported by a woman who claimed that he almost hit her while leaving a local restaurant. Officials said Angle failed a field sobriety test, but he refused a blood test. He was charged with driving under the influence and careless driving, but he denied the charges. On September 9, 2008, Angle was cleared of all charges.  On August 15, 2009, Pittsburgh-based NBC affiliate WPXI reported that Angle had been arrested. His girlfriend stated that she had filed a protection from abuse (PFA) order and that he was stalking her in the Robinson area. Angle was charged with "driving while operating privilege is suspended, prohibited acts-possession, harassment and prohibited acts". Hygetropin, a human growth hormone, was found in his car; Angle maintained that he had a prescription for the drug. On September 15, a District Court Judge dropped the harassment, suspended license, and drug charges against Angle. On November 9, 2009, the PFA charges were dropped after he and former girlfriend Trenesha Biggers reached an agreement to avoid contact with each other.  On March 25, 2011, Angle was arrested in Thompson, North Dakota and charged with "being in control of a motor vehicle while intoxicated" after failing a field sobriety test. Angle later pleaded guilty to the charges and was sentenced on April 20 to one year of unsupervised probation, a chemical dependency evaluation, a $250 fine, $225 in court fees, and a ten-day suspended sentence.  Angle was arrested on September 4, 2011, by Virginia State Troopers for allegedly driving under the influence. Angle was placed in Warren County Jail, before posting $2,000 bail and being released in the early morning. State police revealed that Angle's initial breath test at the scene, where he was stopped by police, showed a blood-alcohol concentration of 0.091 percent, which was above the legal limit of 0.08 percent. The test was later ruled not admissible and when a second test, taken at the police station, showed a blood-alcohol concentration of 0.06, the DUI charge was dropped. Angle was still charged with reckless driving. On November 8, 2011, Angle entered a plea of no contest and was fined $1,500.  On August 2, 2013, Angle was again charged with driving while intoxicated in Decatur, Texas. Later that same day, Angle announced he was immediately entering a rehabilitation center.
Question: Why did he refuse a blood test?
