WATCH Trump's Taunts Continue as Intel Agencies Prepare Russia Hacking Brief

Donald Trump's tweets that some see as undercutting the U.S. intelligence community could damage his relationships with those agencies after he becomes president, experts said.

In the tweets in question he refers dismissively to "the 'Intelligence' briefing," and suggesting that his upcoming briefing was delayed because "perhaps more time needed to build a case."

Trump touted the statements of WikiLeaks founder Julian Assange, who said the Russian government did not give his site the documents it released during the election season.

But all 16 U.S. intelligence agencies have concluded that the Russian government was behind the hacking.

Some former CIA officials — such as 2016 independent presidential candidate and ex-CIA operative Evan McMullin and former CIA and Department of Defense spokesman George Little — have taken to responding to Trump in the same medium, criticizing his comments on Twitter.

McMullin wrote that after the tweet about Assange, Trump "has become a tool of foreign adversaries engaged in a direct assault on our democracy."

Little tweeted today, "Let's stare this reality square in the face: PEOTUS is pro-Putin and believes Julian Assange over the @CIA. On Jan. 20 we will be less safe."

National security experts agree that Trump's tweets could have negative repercussions as he begins to rely more directly on the agencies that make up the U.S. intelligence community.

John Cohen, a former acting undersecretary for intelligence and analysis at the Department of Homeland Security, said Trump and his team's responses to the alleged Russian hacking was "astounding."

"They've yet to be fully briefed by the intelligence community, yet they've issued a number of public statements that have sought to discredit the career professionals in the intelligence community," said Cohen, who now works as an ABC News consultant.

"They've been dismissive of allegations of Russian involvement, and they've mischaracterized information released by law enforcement and intelligence officials. In doing so, they have likely undermined their future relationship with those intelligence and law enforcement professionals."

Susan Hennessey, a fellow in national security law at the Brookings Institution, was quick to warn that it's inaccurate "to think of the intelligence community as a group that gets their feelings hurt very easily" but said the tweets could certainly have a lasting impact.

"Trump has essentially accused the intelligence community of being politicized, that they are producing this information for partisan reasons or to harm him ... That is a really, really significant accusation in the world of intelligence," she told ABC News.

"It does appear as though these tweets may be an attempt by Donald Trump to essentially discredit that report before it's issued," she said of the report ordered by President Obama on alleged Russian hacking. "That's really quite significant — essentially for your incoming boss to undercut the work you do before he takes office. That does have implications for the future of the relationship."

The classified version of the report in question has been finished, according to U.S. officials, and will be presented to Obama on Thursday and Trump on Friday. Both briefings will be conducted by the heads of relevant agencies, including the National Security Agency, the FBI, the CIA and the office of the Director of National Intelligence.

Steve Gomez, a former section chief in the FBI's directorate of intelligence, said Trump's briefing could include an abundance of specifics because of his apparent skepticism.

"If I sensed that the recipient of a briefing is maybe questioning or has some doubt over the conclusions that we reached in our intelligence product, then I would say to our staff who was producing [the information] that, 'Let's provide a greater level of detail in order to show how we've come to those conclusions,'" said Gomez, who is now an ABC News consultant.

"He's not from the government," he said of Trump. "He's not used to receiving classified sensitive briefings that are relying on intelligence from a myriad of sources."

The sources of that information — aside from the intelligence (which Trump sarcastically set in quotes) community — could become an issue as well, Cohen said.

"He seemingly has placed greater credibility in the statements of Julian Assange than the statements of our own director of national intelligence," Cohen said.

He continued, "[Trump] has on his team people who have contacts in and out of government that may provide insights to situations such as the Russian hacking, and while there is value in hearing multiple voices on an issue, it would be highly dangerous for the Trump administration to place a greater sense of credibility on outside voices versus the information that's collected, analyzed, assessed and validated through well-established intelligence community protocol."
