The Department of Homeland Security said the 2020 presidential election was "the most secure in American history."
The statement contradicts President Donald Trump's baseless claims of fraud, which he has sought to spread in the week following the November 3 election.
Trump has refused to concede the election or acknowledge President-elect Joe Biden as the winner.
The Department of Homeland Security broke from President Donald Trump's baseless allegations of a "stolen" election on Thursday and said there is no evidence of fraud.
"The November 3rd election was the most secure in American history," the DHS said in a statement.

The Department's Elections Infrastructure Government Coordinating Council & the Election Infrastructure Sector Coordinating Executive Committees found "no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised."
Trump has refused to concede the election and acknowledge Joe Biden as the President-elect, and has relentlessly sought to spread misinformation and falsehoods about the electoral process.
The DHS said it has the "utmost confidence" in the integrity of the US election system and infrastructure, and urged people to "turn to elections officials as trusted voices as they administer elections."
On Friday, Decision Desk HQ and Insider first called Biden the winner of the 2020 election after he surpassed the necessary 270 electoral votes needed to win, flipping key battleground states like Wisconsin, Pennsylvania, and Michigan.
Trump has called for recounts in several states but Biden has surpassed the necessary margins in order to win the election. A recount is not expected to shift enough votes to change the outcome of the election.

"America, we have confidence in the security of your vote, you should, too," Chris Krebs, Director of the Cybersecurity and Infrastructure Security Agency said in a tweet.
The Trump administration's refusal to acknowledge the president-elect has meant that Biden has gone without necessary privileges that would prepare him and his team to take office in January, including access to presidential daily briefings.
On Wednesday, Republican Sen. James Lankford, of Oklahoma, said he would intervene if President Donald Trump's administration does not grant President-elect Joe Biden access to presidential daily intelligence briefings by Friday.
