Donald Trump's presidential transition team is challenging the veracity of U.S. intelligence assessments concluding that Russia was trying to tip the November election to the Republican.
A senior U.S. official says the CIA has determined with "high confidence" that Moscow's interference in the presidential race was intended to help Trump. The assessment was based in part on evidence that Russian actors had hacked Republicans as well as Democrats but were only releasing information harmful to Hillary Clinton, according to the official.
The official was not authorized to discuss the intelligence assessment publicly and insisted on anonymity.
A spokesman for the Trump transition team questioned both the quality of the intelligence community's information and its motivations. Sean Spicer told CNN that there are "people within these agencies who are upset with the outcome of the election."
Spicer also denied a New York Times report that Republican National Committee systems had been breached during the election.
Sen. Chuck Schumer, a New York Democrat, says he will press for a congressional investigation in the new year.
