President-elect Donald Trump on Thursday questioned the motives behind an NBC News report confirming details of the intelligence briefing given to President Barack Obama on Russian cyberattacks.

"How did NBC get 'an exclusive look into the top secret report he (Obama) was presented?'" Trump tweeted Thursday. "Who gave them this report and why? Politics!"


The network says a senior U.S. intelligence official confirmed leaked details of the report first published in the Washington Post, which states that U.S. intercepts captured Russian officials congratulating themselves on Trump's election win, citing U.S. officials. The overall report makes the case that Russia intervened in the election, NBC News reported.

The president-elect is set to meet with intelligence officials on Friday, when he is expected to be briefed on evidence uncovered by the Russian hacking probe. Trump has repeatedly questioned intelligence agencies' conclusions that Russian operatives were behind several cyberattacks during the 2016 presidential race.

The intelligence report also reveals that U.S. spy agencies had identified "actors" involved in passing stolen Democratic National Committee emails to Wikileaks.

In later tweets, the president-elect took aim at reports that the Democratic National Committee rebuffed FBI requests to directly examine their servers to question the nature of the hacks.

"The Democratic National Committee would not allow the FBI to study or see its computer info after it was supposedly hacked by Russia," Trump tweeted. "So how and why are they so sure about hacking if they never even requested an examination of the computer servers? What is going on?"

BuzzFeed reported earlier Thursday that the FBI was now accusing the DNC of denying them access to their computers, causing delays and forcing them to rely on third-party information for their investigation into alleged Russian hacking.

“The FBI repeatedly stressed to DNC officials the necessity of obtaining direct access to servers and data, only to be rebuffed until well after the initial compromise had been mitigated. This left the FBI no choice but to rely upon a third party for information,” a senior law enforcement official told BuzzFeed in a statement. “These actions caused significant delays and inhibited the FBI from addressing the intrusion earlier.”

The DNC has denied that it ever received such a request from the bureau.

Earlier Thursday, Trump denied that he favored foreign operatives and groups such as WikiLeaks over American intelligence officials.

“The dishonest media likes saying that I am in Agreement with Julian Assange — wrong. I simply state what he states, it is for the people....,” he tweeted, “to make up their own minds as to the truth. The media lies to make it look like I am against "Intelligence" when in fact I am a big fan!”
