Input: Consider Input: UNITED NATIONS (AP) — Secretary-General Antonio Guterres is again calling on the U.N. Security Council to refer Syria to the International Criminal Court  pointing to "serious violations" including blocking aid deliveries and medical care to millions.
 Guterres  said in a report to the council circulated Friday on the humanitarian situation in Syria in December that "accountability for serious violations is a requirement under international law and central to achieving sustainable peace."
During December   he  said  no aid was delivered to over 417 000 people in nine "besieged" locations  and only 60 000 of the nearly 2.5 million Syrians living in "hard-to-reach" areas received humanitarian help.  He  said 95 percent of the besieged population is besieged by Syrian government forces.
 Guterres  said "access for the United Nations and its partners to those people living in besieged and hard-to-reach locations remained a critical concern."
 He  said deliveries of food and other aid remained "extremely challenging" in many areas last month "as a result of active conflict  shifting conflict lines  administrative impediments and deliberate restrictions imposed on the movement of people and goods by the parties to the conflict."

Input: Consider Input: Sportscaster Dick Enberg  Whose Career Spanned 60 Years  Dies At 82
 Legendary announcer Dick Enberg   whose amazing sportscasting career spanned six decades  died Thursday at the age of 82. He did play-by-play for college basketball  college and professional football and Major League Baseball. He also called other sporting events such as boxing  tennis  golf  horse racing and the Olympics.
 Enberg  retired from  his  TV job with the San Diego Padres in October 2016.
The team released a statement on  Enberg 's death:
"We are immensely saddened by the sudden and unexpected passing of  legendary broadcaster Dick Enberg .  Dick  was an institution in the industry for 60 years and we were lucky enough to have  his  iconic voice behind the microphone for Padres games for nearly a decade. On behalf of our entire organization  we send our deepest condolences to his wife  Barbara  and the entire  Enberg  family."
Endberg was known for exclaiming "Oh my!" So much so  that his 2004 autobiography is titled: Dick Enberg  Oh My!
 Enberg 's big break came when he was chosen to call UCLA basketball games. During that nine-year stint  the Bruins won eight NCAA titles.
When asked what was the most historically important event he covered   Enberg  replied  "The Game of the Century." In that 1968 game  the University of Houston Cougars beat UCLA to snap the Bruin's 47-game winning streak.
During his time behind the microphone  Enberg  had many broadcast partners  including Al McGuire  Merlin Olsen and Don Drysdale.
 Enberg 's wife Barbara told the San Diego Union-Tribune that her husband died Thursday morning at his home in La Jolla  Calif.
"Barbara Enberg said the family found out later in the day when  Dick Enberg  failed to get off a flight in Boston  where they were scheduled to meet. She said her husband had appeared to be waiting for a car that was set to shuttle him to the San Diego airport for a 6:30 a.m. flight. " 'He was dressed with his bags packed at the door ' she said. 'We think it was a heart attack.' "

Input: Consider Input: What if  Paul Vallas  runs for mayor of Chicago?
 Vallas  should have run for mayor long ago.  He  should have been elected governor but narrowly lost to the Democratic machineâs choice  Rod Blagojevich  in the 2002 primary. Rod promised  Illinois  he would be a paragon of virtue  and the party hacks sold Blago as a reformer. Roland Burris got into the Democratic primary  pulled black votes away from  Vallas  and later  as a reward  was Blagoâs hand-picked choice to become senator.
So how did that reform work out for Chicago and  Illinois ?
In the years since   Vallas  has spent much of  his  time working to improve public education  particularly for minorities  and spent years working in tough school systems  from Chicago to Philadelphia  in Bridgeport  Conn.  and New Orleans.  He  also spent much time working in Haiti.
Most recently   he âs been chief administrative officer at Chicago State University  put there by Republican Gov. Bruce Rauner even though  Vallas  ran as Democrat Pat Quinnâs running mate in the 2014 election.
 Vallas  has recently established residency in Chicago  the city where  he  was born and raised  his  children.  He  and  his  wife  the parents of cops  are empty nesters now and are leaving the southwest suburbs.  He  just signed a lease in Lincoln Park   Vallas  confirmed to me Tuesday.
Establishing residence isnât just about moving into the city. Itâs about planting a flag  setting a marker  and itâs already being whispered about in political circles  with  Vallas â strengths and weaknesses discussed  all of it laid out against the backdrop of the race for governor.
So I called  Vallas  to ask about  his  move back to Chicago and what it means for the 2019 mayoral race. Though  he  confirmed  his  new residency â and said  he  changed  his  drivers license to reflect  his  new Chicago address â  he  said  he  hasnât yet moved in. Thatâll take a week or so.
Is  he  in? Is  he  out?  Vallas  said  he  didnât want to talk about that. Yet.
OK  I told  him   so Iâll talk about it.
And  as you read this  Iâd assume  he âll send out  his  spinners to drop oppo research against  Vallas  in the news.  He âs got to kill  him  off now  because  he  canât handle  Paul Vallas  in a race for mayor.
