The defense of the US elections from the Obama Administration came amidst hacking fears and allegations of hacking from Russia.
"The Kremlin probably expected that publicity surrounding the disclosures that followed the Russian Government-directed compromises of e-mails from US persons and institutions, including from US political organisations, would raise questions about the integrity of the election process that could have undermined the legitimacy of the President-elect," a senior administration official said.
According to the official, the Federal government did not observe any increased level of malicious cyber activity aimed at disrupting the US electoral process on election day.
"As we have noted before, we remained confident in the overall integrity of electoral infrastructure, a confidence that was borne out on election. As a result, we believe our elections were free and fair from a cybersecurity perspective," the official said.

"That said, since we do not know if the Russians had planned any malicious cyber activity for election day, we don't know if they were deterred from further activity by the various warnings the US government conveyed," he said.
"Nearly three weeks after the presidential election, the numbers showing President-elect Donald Trump's commanding victory are coming more fully into focus. He won 306 electoral votes, the most for a Republican since George H W Bush in 1988," Priebus said.
"He carried 9 of 13 battleground states. Millions of Americans rallied behind his message of rebuilding our country and disrupting the status quo. This was a truly national victory," said Priebus, who has been appointed as the chief of staff by Trump.
Also, Trump won over 200 counties nationwide that Obama won in 2012. This was the most counties won by a Republican since 1984, he said.
Priebus said Trump's message resonated with voters in historically blue states as he registered the first GOP win in Wisconsin since 1984, Pennsylvania and Michigan since 1988 and Iowa since 1984.
"President-elect Donald Trump campaigned in places he knew Republicans have had difficulty winning-Flint, Michigan, charter schools in inner-city Cleveland, and Hispanic churches in Florida-because he wanted to bring his message of economic empowerment to all Americans," he said.
