[Q]: The department's narcotics division began the investigation when a source told them about the group  officials said. The buys were conducted by undercover officers who infiltrated the group  according to Anthony Riccio  chief of the department's organized crime division.
 Riccio  said there are “dozens and dozens of these secret groups  a lot of them used for illegal things  including trafficking the guns and firearms. It's dozens of them out there.”
 He  said many of the guns had defaced serial numbers  making them difficult to trace. “These are guns that are winding up in the South Side  West Side of the city being used in gang shootings ”  Riccio  said.
 He  said the Facebook group selling guns and drugs would not be found by searching and that someone had to vouch for anyone who wanted to join them.
“I absolutely think Facebook has a responsibility to monitor this and for this very reason ”  Riccio  said. “There’s other illegal activities — I want to point out this is phase one — there's other illegal activities going on on Facebook. We're looking at potentially human trafficking  things of that nature as well. There's a lot of tentacles going out here.

Case in point:  Hilborn's daughter  wanted a ponytail like the pop singer Ariana Grande  but felt like  her  mom didn't do the ponytail properly and put it in the wrong place.
" She  came out crying and said  'Ariana Grande's ponytail is here not here '" said  Hilborn   pointing to the place on  her  head where  her  daughter preferred the ponytail to go  not where it ended up.
 Pauline Hilborn  and  her  kids  ages 4 and 7.

Debi  another mother of two in Manhattan  says her 7-year-old has definitely had some tantrums. When I asked  her  son what a meltdown is  he told me it's when you cry a lot. When I asked him to imitate one  he said he keeps screaming until his mom lets him have whatever it is that he wants at that moment.

[Q]: Former White House chief strategist Steve Bannon  broke some bad news to House investigators on Tuesday  announcing that the White House has invoked executive privilege to keep  him  from answering many of their questions.
But executive privilegeâthe presidentâs right to keep certain information from the public so  he  can have frank conversations with aidesâwill not keep  Steve Bannon  from sharing information with Special Counsel Robert Muellerâs team  according to a person familiar with the situation.
âMueller will hear everything  Bannon  has to say â said the source  who is familiar with  Bannon âs thinking.
During a closed-door hearing before the House intelligence committee today   Bannon  reportedly told lawmakers that President Donald Trump has invoked broad executive privilege for the purposes of Congressional inquiries. Because of that   Bannon  refused to answer committee membersâ questions about what happened during the presidential transition and in the White House.
This sweeping understanding of privilege will not impact what  Bannon  tells Muellerâs team  according to our source. (To be sure   Bannon  isn't known for being predictable  and it's possible  his  team may still look for ways to dodge Mueller's queries.)
But it means  he  isnât answering many of Congressâs questions. A source familiar with Bannonâs interview told The Daily Beast that despite the subpoenaâissued by Devin Nunes  the typically Trump-friendly chairman of the committee âBannon  refused to answer questions about events that happened after Election Day.
