Attempted election meddling hit two to three local U.S. areas -O'Brien

Russia and Iran's alleged attempted election interference appears to have involved two to three U.S. cities and counties and affected a "small amount of information," U.S. National Security Adviser Robert O'Brien said on Thursday.

"It was in a couple different municipalities, a very small number, two or three, in different parts of the United States. It was a small amount of information," O'Brien told reporters at the White House.
