CISA published this official statement on November 4, 2020:
Following the final day of voting, Director of the Cybersecurity and Infrastructure Security Agency, Christopher Krebs, issued the following statement:
Over the last four years, the Cybersecurity and Infrastructure Security Agency (CISA) has been a part of a whole-of-nation effort to ensure American voters decide American elections. Importantly, after millions of Americans voted, we have no evidence any foreign adversary was capable of preventing Americans from voting or changing vote tallies.
We are only here because of the hard work of state and local election officials and private sector partners who have focused efforts on enhancing the security and resilience of elections. The United States government supported these partners throughout the election, bringing the full range of capabilities to bear in securing systems and pushing back against malicious actors seeking to disrupt our process and interfere in our election. CISA will continue to support our state and local partners as they move toward their certification deadlines and the official outcome of the 2020 election.
We will remain vigilant for any attempts by foreign actors to target or disrupt the ongoing vote counting and final certification of results. The American people are the last line of defense against foreign influence efforts and we encourage continued patience in the coming days and weeks. Keep calm, continue to look to your state and local election officials for trusted information on election results and visit CISA.gov/rumorcontrol for facts on election security.
