[Q]: Story highlights  Kim  raises possibility of North Korean athletes in Winter Olympics in South Korea
(CNN)  North Korean leader Kim Jong Un  has warned the United States that  his  country's nuclear capabilities are now complete and the nuclear launch button is always on  his  desk.
"The entire mainland of the US is within the range of our nuclear weapons and the nuclear button is always on the desk of my office. They should accurately be aware that this is not a threat but a reality " said  Kim  during  his  annual New Year's Day address  according to a CNN translation of the speech.
"No matter how much America wants to attack us with their military might and nuclear power  they know that now we possess such great nuclear power and therefore they will not dare "  Kim  said  adding that  his  country's greatest achievement of 2017 was the "historic accomplishment of completing our nuclear capabilities."
Since coming to power   Kim  has overseen a dramatic increase in the pace of North Korea's missile program. As of February last year  Pyongyang has fired off 23 missiles  improving its technology with each launch. In September  the regime carried out its sixth and most powerful nuclear test.
Euan Graham  director of the International Security Program at the Lowy Institute  told CNN that  Kim 's nuclear button comment is "effectively just noise."

[Q]: Dr. Anna Konopka  told Merrimack Superior Court Judge John Kissinger on Friday that  her  inability to practice is putting  her  patients at risk  because they are having a hard time finding another physician and fill their prescriptions.
But Assistant Attorney General Lyn Cusack says  Konopka 's request should be denied  arguing the doctor has been given plenty of time to close her practice and help patients find other doctors. If she wants to get her license back  Cusack says  Konopka  could file for reconsideration with the Board of Medicine.
Kissinger says he will take  Konopka 's request under advisement.
 Dr. Anna Konopka  voluntary gave up  her  license in October after the state Board of Medicine challenged  her  record keeping  drug prescribing practices and medical decision making. Part of the problem is that the New London doctor doesn't use a computer and therefore doesn't participate in the state's mandatory drug monitoring program.
 Konopka  has been granted an emergency court hearing on Friday to try to convince a judge that  she  deserves to get  her  license back. Though  she  insists  her  paper record keeping system works fine   she  says  she  would be willing to learn to use a computer.

[Q]: Former Mississippi Gov. Haley Barbour  says  he  will pay a fine after being arrested with a loaded handgun in  his  briefcase as  he  went through an airport security checkpoint.
Barbour -- Republican National Committee chairman in the mid-1990s and governor from 2004-12 -- told The Associated Press on Tuesday he was trying to board a flight Jan. 2 from  Jackson  to Washington. He said he forgot he was carrying the gun  which he had put in his briefcase after an assistant removed it from his car days earlier.
"This was absentmindedness and nobody's fault but mine " said  Barbour   70  who lives in Mississippi and frequently travels to Washington for  his  job as a lobbyist.
Transportation Security Administration spokeswoman Lisa Farbstein said a TSA officer working at an X-ray machine at a checkpoint at Jackson-Medgar Wiley Evers International Airport spotted a .38-caliber revolver  loaded with five bullets  in a passenger's carry-on bag. TSA contacted airport police  who arrested the passenger. The TSA would not release the passenger's name  but Farbstein confirmed it was a former governor  and  Barbour  confirmed to AP that it was he.
 Barbour  said  he  did not dispute Farbstein's use of the word "arrest " though  he  said  he  was not handcuffed and no mugshot photo was taken.  Barbour  described the TSA officers and the airport police as "very nice but very professional."
"They did exactly what they should have done  which was treat me like anybody else "  Barbour  said.
 Barbour  said the gun was confiscated and  he  boarded  his  flight to Washington.
"Next time  I'll be more observant about getting stuff out of my briefcase "  he  said.
