President-elect Donald Trump said he didn't believe reports that intelligence agencies cocluded Russia intervened in the election on his behalf.
Speaking during an interview with Fox New Sunday, he said it was "just another excuse", and blamed Democrats for putting out the media reports.
Earlier this week, a senior intelligence official told Reuters intelligence agencies have concluded with "high confidence" that not only did their Russian counterparts direct the hacking of Democratic Party organisations and leaders, but they did so to undermine Democratic candidate Hillary Clinton.
Significant Republican figures have joined the Democrats in voicing their concerns over the reports, including Senator John McCain.
"For years, foreign adversaries have directed cyber attacks at America's physical, economic and military infrastructure, while stealing our intellectual property. Now our democratic institutions have been targeted," US senators said in a statement.
"Recent reports of Russian interference in our election should alarm every American."
In the Fox News interview, Mr Trump also questioned whether the United States should continue its "One China policy" unless Beijing makes concessions on trade and other issues.
