Johnson did admit that there was a delay between the time it took for the FBI to learn about the cyberattack at the Democratic National Committee (DNC) and the time it took for him to learn about the discovery as DHS secretary.

…Johnson said that he’s “not sure” he had authority at DHS to investigate whether votes were altered. He said DHS does not engage in vote recounts and there are others who have that responsibility.

…Johnson explained that one of the candidates, President Trump, was claiming that the election would be “rigged” and that by accusing Russia of being responsible for the cyber intrusions would undermine the integrity of the process. That comment, therefore, prevented the administration from going public about Russia sooner, he suggested.

…He said his recollection is that the FBI first discovered the intrusion into the DNC and he said “I recall very clearly that there was a delay between that initial contact” with the DNC and when the report got to him as DHS secretary.
