 Yumkella acknowledged that IT companies must take an active role in mitigating e-waste but as the saying goes  it's important not to throw out the baby with the bath water.

Q: Sen. Bob Corker (R-TN)  speaks with reporters after announcing  his  retirement at the conclusion of  his  term on Capitol Hill in Washington  U.S.  September 26  2017. REUTERS/Aaron P. Bernstein
WASHINGTON (Reuters)  - U.S. Senator Bob Corker   the influential Republican chairman of the Senate Foreign Relations Committee  said on Tuesday he will not run for re-election  a blow to a party already struggling to balance divisions between mainstream and more populist wings.
An establishment Republican   Corker  has been criticized from the right  and a conservative activist had already announced a primary challenge. But he was expected to keep the seat  and had amassed a $7.5 million campaign war chest.
 Corker  has ruled out running for governor of Tennessee.
âI have no idea what Iâm going to do. No idea whatsoever â  Corker  said in an interview. But he said he was not leaving out of frustration over deep party divides that have often paralyzed Congress.
 Corker  announced  his  retirement on the day of the failure of the latest Republican effort to repeal former Democratic President Barack Obamaâs healthcare law.
âI am not going to be one of the people who leaves here badmouthing what is one of the greatest privileges of oneâs life â  Corker  said.
He said he realized he was ready to retire on Aug. 24 during a factory groundbreaking in Clarksville  Tennessee  and almost announced his decision at least twice before Tuesday.  Corker  said that he made his announcement now to allow a strong candidate time to enter the Senate race.
 Corker  is the first senator to announce  his  retirement ahead of the 2018 mid-term elections  when one-third of the 100-seat chamber will be up for grabs. Tennessee is a solidly Republican state and the party  which currently holds a 52-seat majority in the Senate  is favored to keep his seat.
In his official announcement   Corker  said that âafter much thought  consideration and family discussionâ over the past year  he and his wife Elizabeth âhave decided that I will leave the United States Senate when my term expires at the end of 2018.â

CLASHES WITH  TRUMP
In August  after Trumpâs much-criticized reaction to violence at a white supremacist rally in Virginia   Corker  told reporters in  his  home state Tennessee that Trump had not been able to demonstrate the âstabilityâ or competence that  he  needed to be successful as president.
After the exchange  the two men had an hour-long meeting at the White House this month that  Corker  has described as a wide-ranging and friendly discussion.
 Corker  will remain chairman of the Foreign Relations Committee until he leaves in January 2019. He said he wanted the panel to address issues including Secretary of State Rex Tillersonâs State Department reorganization  food aid reform  and the fight against human trafficking and modern slavery.
 Corker  said the committee would address the international nuclear agreement with Iran  as Trump faces a mid-October deadline for deciding whether to certify that Tehran is complying with that pact. That decision could force Congress to decide whether to reimpose sanctions.  Corker  would not say whether Trump had decided to certify or not.

Q: When Ames Mayfield's Cub Scout den met with a Colorado state senator last week  the 11-year-old came prepared with a long list of typed-up questions. He excitedly raised his hand to ask his first one.
 Ames  pressed the Republican state senator  Vicki Marble  on an issue he knew was important to her: gun legislation. The Cub Scout in Broomfield  about 20 miles north of Denver  asked her a slew of questions about previous bills she had sponsored in support of the right to bear arms  and he wasn't shy about inserting his opinion.
"I was shocked that you co-sponsored a bill to allow domestic violence offenders to continue to own a gun "  Ames  said  according to a video posted to YouTube by  his  mother. "Why on earth would you want someone who beats their wife to have access to a gun?"
After  Ames 's questions went on for more than two minutes  a leader in his group cut him off to allow the state senator to answer. Both the senator and the leader commended him for his "thorough" list of questions.
But after the meeting  the leader of  Ames 's Cub Scout pack  which oversees various dens  requested a meeting with his mother. The leader told  Ames 's mother  Lori Mayfield  that her son was kicked out of his Cub Scout den  the mother said in an email to The Washington Post.
The son's den leader was apparently upset over  Ames 's questions  particularly the one on gun control   Mayfield  said. The mother was told her son's question was disrespectful and too political.
"I had to go home and tell my son he was kicked out  " Mayfield  said. "My son was heartbroken because he really liked this den leader and couldn't understand why his question was inappropriate."
 Ames  was less than four months away from transitioning from the Cub Scouts to the Boy Scouts   his  mother said.
The Scouts did not explicitly say  he  was kicked out of the den. In a statement to The Post and local media outlets the Denver Area Council of the Boy Scouts said only that he remains a member of the larger pack  and that the organization is working with the family to offer him options that will "allow him to continue his Scouting experience in a way that fits his and his family's needs."
But local news reports of  Ames 's apparent removal from his den drew anger across social media  with many arguing that  Ames  was punished for asking tough questions of a state lawmaker. After all  the den had specifically assigned the scouts to prepare questions for the senator.
 Ames 's story drew the attention of gun control advocate and former Democratic Rep. Gabrielle Giffords of Arizona  who was shot in the head by an assailant in 2011  suffering a severe brain injury.
"This is exactly the kind of courage we need in Congress " Giffords tweeted Thursday. " Ames   call me in 14 years. I'll campaign for you."
Giffords's husband  astronaut Mark Kelly  called  Ames  and his mother Thursday night to talk about what happened  according to Fox 31.
The focus of the Cub Scouts' assignment   Mayfield  said  was to meet with a government leader and discuss an important issue facing the community. Cub Scouts were instructed to decide on one or two questions  and to be prepared to ask the official about an issue in the local news.
 Ames  researched the senator before the meeting and decided he would focus his questions on gun control  his mother said. After all  the majority of the videos on Marble's site deal with gun rights legislation.
"Given that the Las Vegas shooting happened  I felt that it should be a reasonable thing to ask "  Ames  told a Denver Fox affiliate. "I don't feel like I did anything wrong."
