Example Input: "Of course we are very disappointed  and I can also say in Marco's name that he feels this verdict is unjust " Weiss' father  Ralf Jahns  told reporters in the family's home town of Uelzen  Germany.
 "This verdict says nothing about Marco's guilt or innocence " his mother  Martina  said  and suggested the court's motivation had been that "the long time in investigative custody had to be justified."
 The verdict follows a lengthy trial that dragged on as the court demanded various reports on the girl's physical and mental condition from British authorities. Some prosecutors and judges in the panel of three overseeing the case were also changed  delaying proceedings. It began as a closed-door trial  with Weiss still a minor and identified only as Marco W. It was later opened to journalists.
 Weiss maintained that he and the girl became close while in the Mediterranean resort of Side  near Antalya  and one night ended up in the girl's hotel bedroom where they had physical contact but no intercourse. He also said the girl had lied about her age and said she was 15 -- the age of consent in Turkey.
 He was arrested the next day  after the girl's mother filed a complaint with Turkish police  and he was held for eight months in custody until being allowed to return home after an appeal from German Foreign Minister Frank-Walter Steinmeier.
 On his return  Weiss wrote a book -- "Marco W. -- My 247 days in a Turkish prison" -- detailing his time inside the jail in Antalya.
 WeissWeiss' lawyer said he would appeal Wednesday's conviction  arguing that his client should have been cleared on grounds of insufficient proof and shortfalls in the investigation.
 "Marco Weiss should have been acquitted " Mehmet Asim Iplikcioglu said. "We will fight for that until the end."

Example Input: (CNN)  Rob Porter  was involved in serious discussions to be promoted when  he  abruptly resigned from the White House last week amid allegations that  he  abused  his  two ex-wives  multiple sources familiar with the matter tell CNN.
 His  anticipated elevation further highlights how top White House officials were willing to overlook indications from the FBI that there were potential abuse allegations in  his  background in exchange for professional competence in a tumultuous West Wing.
 Porter  had been actively lobbying to take on new policy portfolios outside the traditional scope of the staff secretary  one person familiar with the matter said  which included speechwriting duties and a role in planning policy rollouts. Neither of those tasks is traditionally carried out by the staff secretary.
One of the areas  Porter  was set to delve further into was trade policy  according to the person.  Porter  was a regular attendee at a weekly trade meeting among top-level administration officials.
 He  was also being considered for the deputy chief of staff position  another source familiar with the situation said. CNN reported Friday that Jim Carroll  who served as the deputy chief of staff for less than three months  was stepping down to helm the Office of National Drug Control Policy.
