The majority of American voters believe Russian interference with the 2016 presidential election had no influence on its outcome, according to a new poll by Fox News.

Fifty-nine percent of all voters polled by Fox News said they don’t think Russian hacking made a difference in the election, while 32 percent believe Moscow helped President-elect Donald Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

Opinions were split along partisan lines, with 82 percent of Republicans, 64 percent of independents and 36 percent of Democrats saying Russia’s interference had no impact.

A secret CIA assessment concluded Russia hacking was intended to sway the election in Trump’s favor.

Trump himself has cast doubt on the CIA conclusion, tweeting that if he lost and claimed that the Russians helped Democratic nominee Hillary Clinton Hillary Diane Rodham ClintonDemocratic groups using Bloomberg money to launch M in Spanish language ads in Florida The Hill's Campaign Report: Presidential polls tighten weeks out from Election Day More than 50 Latino faith leaders endorse Biden MORE, it would be called a conspiracy theory.

Can you imagine if the election results were the opposite and WE tried to play the Russia/CIA card. It would be called conspiracy theory! — Donald J. Trump (@realDonaldTrump) December 12, 2016

Republican leaders in the Senate, however, have called the CIA hacking "an American issue," rather than a partisan one.

A growing number of Democratic electors — and one Republican elector — have also asked for a briefing ahead of their vote on Monday.
