[EX Q]: Ahead of a potential First Amendment showdown Wednesday in the cityâs most closely watched murder case   a lawyer for independent journalist Jamie Kalven  says an attempt to force  his  testimony amounts to little more than an âunjustified fishing expeditionâ by indicted Chicago police Officer Jason Van Dykeâs attorneys.
Van Dykeâs attorneys have alleged that  Kalven  â the first journalist to detail the fatal shooting of Laquan McDonald â received leaked documents containing legally protected information.
âGiven the fatal lack of evidence to support Defendantâs lynchpin factual claim  one is left to wonder the perceived point of (his) efforts â Matthew Topic   Kalven âs attorney  wrote in a document filed Tuesday.
 Kalven  is expected to be in court for the 9 a.m. Wednesday hearing  but it is unclear if he will be called to the the stand. He has vowed not to disclose sources.
None of the filings on this issue by Van Dykeâs legal team have been made public. But at a court hearing in October  the officerâs lead attorney  Daniel Herbert   alleged that  Kalven  obtained leaked documents containing information protected by long-standing legal precedent from being used against Van Dyke in a criminal case.
Herbert suggested that  Kalven  used that information to interview witnesses â with the assistance of the FBI â in a way that shaped the witnessesâ statements to authorities.
In court filings   Kalven âs attorney called Herbertâs efforts âscattershot  unsupported and irrelevant.â The only reports about the case in  Kalven âs possession were obtained from the city through Freedom of Information Act requests more than a year after the shooting  according to Topic.
In addition  as a journalist   Kalven  cannot be forced to disclose  his  sources except in certain specific circumstances   his  attorney stated.

[EX Q]: Pyeongchang (South Korea) (AFP)  â American prodigy Nathan Chen  became the first figure skater to land six quads as  he  set an Olympic record in the free skate at the Pyeongchang Winter Olympics on Saturday.
The 18-year-old had bombed on Friday in a nervy short programme that left  him  languishing in 17th place going into the decisive day.
But  Chen  could yet grab a medal after a remarkable free skate that earned  him  215.08 points  one of the highest scores ever seen in the sport.
 Chen  did it on the back of six quads â four rotations in the air â breaking  his  own record of five set last year.
âI have been working on it for a while. Itâs never really fully come together â  Chen  said.
