The White House on Friday declined to answer questions about how U.S. intelligence reports on Russia’s hacking into Democratic emails found their way to NBC, just hours after President-elect Trump tweeted that he wants a congressional probe into the incident.

“I can’t speak to the inner workings of the intelligence community, particularly as it relates to the compiling of this specific report,” press secretary Josh Earnest said Friday, referencing a report about Russian cyberactivity that President Obama has already reviewed. “For questions about how the intelligence community has handled specific pieces of information, you should go talk to them about that.”
