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.

 Former first lady Michelle Obama  had a busy schedule during  her  years in the White House.
To make sure  her  personal life didn't get the short end of the stick   Obama  would plan out  her  year  adding date nights  vacations and even workouts  before signing on to any meetings or events.
"Oftentimes we don't do that as professionals  " Obama  said. "We schedule work before we schedule us."
 Former first lady Michelle Obama   speaking at Klick Health's Muse event in New York  said that was especially challenging after uprooting  her  family while  her  children were young to move to the White House.
"What we learned we had to do is start prioritizing us alongside â and often before â the work "  Obama  said.
"Oftentimes we don't do that as professionals. We schedule work before we schedule us "  Obama  said. But it doesn't have to be that way  she said. "The truth is even when you schedule your family  there's still plenty of time for work. But we don't plan like that."
"We always scheduled family dinners. He was always home in time to sit down for that family dinner "  Obama  said. "We had our regular vacations and Barack never missed a parent-teacher conference."

Kirti Tiwari was elated when he learned last year that he'd been nominated by his higher-ups at the United States Army to become a NASA astronaut. Tiwari  who first enlisted in the military in 2014  was excited by the prospect of what he felt was a huge career advancement opportunity. "I always had this idea of wearing a uniform " he says.
Tiwari  who first came to the U.S. on a student visa  qualified for the program on account of both his fluency in Hindi and his academic performance. Prior to enlisting  he had earned a master's degree in molecular biology from the University of Houston  and worked as a research specialist at Baylor College of Medicine and Texas Children's Hospital. He enlisted in June of 2014; one year later  he was naturalized through the Army after completing basic combat training and advanced individual training. In 2016  after a months-long process   Tiwari  simultaneously applied for a NASA astronaut candidate program through the Army and a military microbiologist posting.
A few months later   Tiwari  learned the Army had selected  him  as a microbiologist and also nominated  him  for the NASA astronaut program.  Tiwari  was working as an Army health-care specialist at a military base near Tacoma  Washington  where  he  was told that  he  had been retroactively declared ineligible for either career opportunity—precisely because  he  was a foreign-born recruit.
Some soldiers find themselves unable to enter the U.S. Army medical department's programs for dentistry  physician assistantship  and other health professions. "Some people are being told they can't apply to regular officer-producing programs "  Tiwari  says. "Sometimes they are told the previous restriction has been removed  only to receive a clearance but no commission."
Despite this  the Department of Defense says it is still processing security clearances for MAVNIs  and claims there is reason for optimism for soldiers in the program.  Tiwari  remains hopeful about the approval of  his  own pending security clearance— he  plans to move to Georgia this winter to serve as an Army microbiologist in the medical service corps.  He  will also press forward with  his  lawsuit   he  says as a way to seek justice for fellow soldiers.
For now  foreign enlistees remain in limbo  hoping the Department of Defense will determine that they're fit to serve. "I really hope one day I can become an astronaut "  Tiwari  says. For now   his  dream job has been grounded.
