[Q]: DC Entertainment on Saturday announced the company is investigating  group editor Eddie Berganza  after Buzzfeed reported on his alleged history of predatory behavior.
Former writer Liz Marsham said  Berganza  kissed her during a party and groped her at a company gathering at a bar in 2006.
Another DC Comics employee reported a similar encounter. Joan Hilty  who is openly gay  said  Berganza  tried grabbing her at the same bar during a separate incident  according to Buzzfeed.
At least five women confronted DC Comicsâ HR with their objections after learning  Berganza  was being considered for an executive editor promotion. He was promoted anyway  the site said.
 Berganza  was demoted to group editor in 2012 after a similar allegation that he forcibly kissed a married freelance writer during the WonderCon convention.
Despite the demotion   Berganza  went on to oversee projects related to Superman and Wonder Woman.

[Q]: State Department spokeswoman Heather Nauert said Secretary of State Rex Tillerson and Russian Foreign Minister Sergei Lavrov spoke by telephone on Tuesday  after Washington and the United Nations both announced sanctions against North Korea in recent days.
Moscow said Lavrov told  Tillerson  “Washington’s aggressive rhetoric” and beefing up of its military presence in the region had heightened tension and was unacceptable.
 Tillerson  has emphasized diplomacy but the administration of President Donald Trump has repeatedly warned that all options  including military ones  are on the table regarding North Korea.
In October  Trump said  Tillerson  was “wasting his time” trying to negotiate with North Korea and this month the White House followed up an offer by the secretary of state to begin talks with no pre-conditions by saying that no negotiations could be held until North Korea improves its behavior.
