New York (CNN Business) BuzzFeed says its sources are "standing behind" the bombshell report about the special counsel investigation.

"We're being told to stand our ground. Our reporting is going to be borne out to be accurate, and we're 100% behind it," investigative reporter Anthony Cormier told CNN's Brian Stelter on "Reliable Sources" Sunday.

The information was attributed to two unnamed "federal law enforcement officials" involved in the investigation.

Cormier, who wouldn't reveal his sources when asked, said the story had been in the works for months and went through a "rigorous" vetting process. The story was reviewed by at least three editors, Smith said.
