Question is— who let her in, in the first place? There should be a “vetted” procedure and “layers” just like the WH or anywhere else. Not a “walk in” with a good story.
imho this was a “breach” perhaps an enabled one (and thus reflecting on certain leadership). Inasmuch as the woman was NOT there during Xi Ping’s upcoming visit, would say a complete total scan of the premises is probable.
chi-coms want to take us down velly velly much.
I would think the Chinese had a total scan of the premises by 2016, likely a lot earlier.
We will probably never know what she was up to.
