Q: Oscar Cortez   46  originally from El Salvador  is a plumber who has built an American life in the 17 years he has had temporary protected status. The U.S. government will terminate the program for an estimated 200 000 Salvadorans in this country  people with knowledge of the plan said Monday. (Bonnie Jo Mount/The Washington Post)
 Oscar Cortez  feels like  he  has an ordinary American life.  He  carries a Costco card.  He  roots for the Boston Red Sox. And five days a week   he  rises before dawn  pulls on four shirts and two pairs of pants  and ventures into the frigid air to work as a plumber  a good job that pays for his Maryland townhouse and his daughtersâ college fund.
The U.S. government opened the door to this life in 2001 when it granted  Cortez  and about 200 000 other migrants from El Salvador Temporary Protected Status (TPS)  a provisional reprieve from deportation that has allowed them to work legally in the United States for 17 years.
At 15th and L streets NW in Washington   Cortez  saw the news on  his  mobile phone while taking a break from laying copper pipe at the construction site of the new Fannie Mae headquarters.
Many Salvadorans say they will try to stay in the United States illegally â a fate they find more bearable than facing the rampant gang violence in their homeland.  Cortez  said  he  visited  his  parents in 2016 for the first time since  he  left and was shocked to see that the house had six locks on every door to ward off burglars. People  he  knew had left or died. Strangers stared at  him  on the street.
âI felt like a foreigner in my own land â  he  said. âEveryone is looking at  you  like youâre from outer space.â
Both men said they are hoarding their savings in case they lose their jobs along with their protected status.  Cortez  has put off replacing  his  old Mitsubishi Montero  with 150 000 miles and a sputtering engine.
Like many TPS recipients  they say they will try to obtain legal residency.  His  wife is a legal resident  and  Cortez  hopes she will someday be able to sponsor  him . Contreras said he is trying to get a green card through his wife  a U.S. citizen. But there are no guarantees.
 Cortez  nodded. âWeâll lose our jobs â he said. âWeâll lose it all.â

Q: "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."

Q: "Storm clouds are gathering" over  the Korean Peninsula  Defense Secretary Jim Mattis  declared Friday. And as diplomats try to resolve the nuclear standoff   he  told soldiers that the U.S. military must do its part by being ready for war.
Without forecasting a conflict   Mattis  emphasized that diplomacy stands the best chance of preventing a war if America's words are backed up by strong and prepared armed forces.
"My fine young soldiers  the only way our diplomats can speak with authority and be believed is if you're ready to go "  Mattis  told several dozen soldiers and airmen at the 82nd Airborne Division's Hall of Heroes  his last stop on a two-day pre-holiday tour of bases to greet troops.
 Mattis'  comments came as the U.N. Security Council unanimously approved tough new sanctions against North Korea  compelling nations to sharply reduce their sales of oil to the reclusive country and send home all North Korean expatriate workers within two years. Such workers are seen as a key source of revenue for North Korean leader Kim Jong Un's cash-strapped government.
At Fort Bragg  Mattis recommended the troops read T.R. Fehrenbach's military classic "This Kind of War: A Study in Unpreparedness " first published in 1963  a decade after the Korean War ended.
Asked about recent reports that families of U.S. service members in South Korea might be evacuated   Mattis  stressed  his  belief that diplomacy could still avert a crisis.  He  said there is no plan now for an evacuation.
"I don't think it's at that point yet "  he  said  adding that an evacuation of American civilians would hurt the South Korean economy.  He  said there is a contingency plan that would get U.S. service members' families out "on very short notice. "
Mattis  said  he  sees little chance of Kim disrupting the Winter Olympics  which begin in South Korea in February.
"I don't think Kim is stupid enough to take on the whole world by killing their athletes "  he  said.
 Mattis  repeatedly stressed that there is still time to work out a peaceful solution. At one point  he  said diplomacy is "going positively." But  he  also seemed determined to steel U.S. troops against what could be a costly war on the Korean Peninsula.
"There is very little reason for optimism "  he  said.
