Q: On Friday  Sen. Dianne Feinstein (D-CA) said she will introduce legislation that would raise the minimum age requirements for purchasing a rifle from a gun dealer.
 Feinstein 's declaration comes after 17 people were killed Marjory Stoneman Douglas High School in Parkland  Florida on Wednesday.
 Feinstein 's proposal received a mixed reaction.
I plan to introduce a bill to require ALL firearms purchases from gun dealers be restricted to individuals who are at least 21 years old. If you can’t buy a handgun or a bottle of beer  you shouldn’t be able to buy an AR-15. — Sen Dianne Feinstein (@SenFeinstein) February 17  2018

Q: We have some news now on how the Trump administration is pushing back against illegal immigration. The administration has for months talked about separating immigrant families at the border as a way of discouraging them from coming in the first place. A federal lawsuit filed on Monday says federal agents are increasingly doing that  and the idea has outraged activists. The plaintiff is an undocumented Congolese woman who's being detained in San Diego while her 7-year-old daughter is being held 2 000 miles away at a shelter in Chicago.  NPR's John Burnett  has the story.
 JOHN BURNETT   BYLINE: In recent years  the Department of Homeland Security has attempted to discourage asylum-seekers from coming to the U.S. Under Obama  they detained some unauthorized families in camps in South Texas rather than release them in the U.S. while their cases are heard. The Trump administration has gone even further. It has arrested immigrant parents in the U.S. who paid smugglers to bring their children across the border  and it wants to expand detention space. Now comes the most extreme measure yet  family separation.
 BURNETT : That's Lee Gelernt  deputy director of the ACLU's National Immigrant Rights Project. He's representing a 39-year-old mother who traveled from the Democratic Republic of Congo to Mexico with her 7-year-old daughter. They surrendered to immigration agents near San Diego in December. They said they were fleeing violence in Congo and asked for asylum. She's being held apart from her daughter. They're only able to speak by phone.
 BURNETT : A spokeswoman for Homeland Security declined to give a reason why the child was taken from her mother  saying only the agency does not comment on cases under litigation. The practice of separating undocumented families to discourage them from coming is not a formal stated policy of the administration  but immigrant activists say it's been quietly growing in frequency along the Southern border. Katharina Obser is with the Women's Refugee Commission.
 BURNETT : Lutheran Immigration and Refugee Services has documented 53 incidents of family separation in the last nine months  mostly Central Americans. They say they're fleeing rampant gang violence. But the administration believes most of them are gaming the system  and it wants to stop the flow  first  because the trek is dangerous for young children. And  second  Matt Al Bent's  an official with ICE removal operations  told NPR...
 BURNETT : Immigration lawyers say the strategy could work. Mothers may drop their cases and go home to be reunited with their children. But is that a reasonable way to curtail illegal immigration? Dr. Lisa Fortuna  director of Child and Adolescent Psychiatry at the Boston Medical Center  is an expert on the impact of trauma on immigrant families. She's submitting an amicus brief in the ACLU lawsuit.
 BURNETT : The lawsuit claims that immigration agents violated the Congolese woman's constitutional right to due process. It asks the government  if it's going to detain a mother and child during the asylum process  at least allow them to be together.  John Burnett   NPR News. Transcript provided by NPR  Copyright NPR.

A: To Curb Illegal Immigration DHS Separating Families At The Border

Q: LOS ANGELES (AP)  â Tom Petty  an old-fashioned rock superstar and everyman who drew upon the Byrds  the Beatles and other bands he worshipped as a boy and produced new classics such as âFree Fallin â² âRefugeeâ and âAmerican Girl â  has died.
 Petty  passed away Monday night at UCLA Medical Center in Los Angeles after  he  suffered cardiac arrest at  his  home in Malibu  California  spokeswoman Carla Sacks said. He was 66.
 Petty  and his longtime band the Heartbreakers had recently completed a 40th anniversary tour  one he hinted would be their last.
âIâm thinking it may be the last trip around the country â  Petty  told Rolling Stone last year. âWeâre all on the backside of our 60s. I have a granddaughter now Iâd like to see as much as I can. I donât want to spend my life on the road. This tour will take me away for four months. With a little kid  thatâs a lot of time.â
Usually backed by the Heartbreakers   Petty  broke through in the 1970s and went on to sell more than 80 million records. The Gainesville  Florida  native with the shaggy blond hair and gaunt features was loved for his melodic hard rock  nasally vocals and down-to-earth style. The Rock and Roll Hall of Fame  which inducted Petty and the Heartbreakers in 2002  praised them as âdurable  resourceful  hard-working  likeable and unpretentious.â
 Petty  didnât just sing about not backing down   he  lived it. In 1979   he  was enraged when  his  record label was sold and  his  contract transferred. Stating that  he  would not be âbought and sold like a piece of meat â  he  self-financed what became âDamn the Torpedoesâ and declared bankruptcy rather than allowing  his  label  MCA  to release it.  He  eventually reached a new deal with MCA  for better terms. In the early 1980s   he  was again at war with MCA  this time over the labelâs plans to charge extra money  a dollar higher than the standard $8.98  for  his  album âHard Promises.â  He  again prevailed.
 Petty  was both a musician and obsessive fan  one who met  his  childhood heroes and lived out the fantasies of countless young rock lovers.  He  befriended Byrds leader Roger McGuinn and became close to George Harrison  who performed on âI Wonât Back Downâ and joined Petty  Bob Dylan  Roy Orbison and Jeff Lynne in the impromptu super group the Traveling Wilburys.  Petty  inducted Harrison into the Rock Hall in 2004; two years earlier Dylanâs son Jakob inducted  Petty . In the 1980s  Petty and the Heartbreakers supported Bob Dylan on a nationwide tour.
He would speak of being consumed by rock music since childhood  to the point where father  whom  Petty  would later say beat him savagely  thought he was âmental.â Awed by the chiming guitars of the Byrds  the melodic genius of the Beatles and the snarling lyrics of Dylan  he was amazed to find that other kids were feeling the same way.
By his early 20s   Petty  had formed the group Mudcrutch with fellow Gainesville natives and future Heartbreakers (guitarist) Mike Campbell and (keyboardist) Benmont Tench. They soon broke up  but reunited in Los Angeles as the Heartbreakers  joined by bassist Ron Blair and drummer Stan Lynch. Their eponymous debut album came out in 1976 and they soon built a wide following  fitting easily into the New Wave sounds of the time.
The world changed more than  Petty  did over the past few decades. In 2014  around the time  he  received an ASCAP Founders Award   he  told The Associated Press that  he  thought of  himself  as âkind of a music historian.â
âIâm always interested in the older music  and Iâm still always discovering things that I didnât know about â  he  said. âTo be honest  I really probably spend more time listening to the old stuff than I do the new stuff.â
