We're gathering different points of view about this all weekend  and we're going to start with  Congressman Ryan Costello .  He  is a Republican.  He 's in  his  second term representing Pennsylvania's 6th District  which is northwest of Philadelphia. You might remember that reviving the steel industry was one of President Trump's campaign promises  and that's one of the factors cited in Mr. Trump's victory in Pennsylvania in the 2016 election. But  he  didn't win  Mr. Costello 's district  where Hillary Clinton won narrowly.
And  Congressman Costello  is with us now. Congressman  thanks so much for speaking with us.
RYAN  COSTELLO : Great to be with you. Strange bedfellows is an apt description for sure.
 COSTELLO : On the circumference of it  yes. Additionally - little known fact - the only domestic keg company in the country is in my district. And I spoke with them yesterday  and they are extremely happy with the decision because of what the price of aluminum from China is. So there's a lot of crosscurrents in terms of who supports this as well as - some who would normally support the president's economic policies have very deep-seated concerns over it.
 COSTELLO : Well  this is certainly doubling down to those who supported  him . And  he 's consistent here with whom  he  is looking out for. It does remain to be seen what the actual policy is. This is - this could - may at the moment be similar to withdrawal of the Paris accord - right? - which pleased  his  supporters but has not yet happened. So it remains to be seen formally what steps are taken.
MARTIN: That's  Representative Ryan Costello .  He  represents the 6th District of Pennsylvania. We reached  him  in Chester County. Congressman  thanks so much for speaking with us.
 COSTELLO : Thank you. Have a good day.
Ryan Costello

"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."
