DoJ charges a former CIA officer with unlawfully retaining classified information. Arrested at JFK upon arrival from Hong Kong. 
Too little, too late, but this is a counter-counterintelligence coup. (And another naturalized US citizen of Chinese origin implicated.) nytimes.com/2018/01/16/us/…
Here's the PDF of the case file: assets.documentcloud.org/documents/4351… 
This is... extremely bad and explains why CIA assets in China began dropping like flies in recent years. 
This is a huge story. More details here: nbcnews.com/news/us-news/e…
This is the interesting bit. Maybe a lack of evidence is what keeps him from getting slapped with espionage charges, but I suspect it is maybe related to sources/methods concerns. (Doubt this is the bottom of it all.) 
And if you don't know what I'm talking about above re: PRC's counterintelligence coup, read this NYT story from last year: nytimes.com/2017/05/20/wor…
A problem with the Times report is that neither DoJ's press release nor the attached arrest affidavit actually say this.
