Facebook COO Sheryl Sandberg has released the opening statement she'll deliver to Congress Wednesday regarding online election meddling saying, "we know we can't stop interference by ourselves."

"We don't have all the investigative tools the government has, and we can't always attribute attacks or identify motives," Sandberg plans to say, according to prepared written testimony provided to CNBC.
