Jim Sciutto is answering questions re: Russia & the CNN special.

Very interesting.

@jimsciutto how secure is US critical infrastructure? Is there a plan in place in case of an attack?#RussianConnection

Not clear. NSA has told me Russia and China have both breached critical US infrastructure. US has done the same to them #RussianConnection https://t.co/UNoi2cGsNT
