I used "explosive" because that was how it appeared in the court filings. Without knowing the precise mixture, it could result as either something to cause a conflagration, or a detonation.
Calling it misinformation is somewhat disingenuous when not all the information is publicly available.
Your quote literally calls it a "destructive device", not an explosive, which is a term of art including mostly non-explosive things. The material in question is specified in the article. It is not explosive in any configuration as an incontrovertible matter of elementary chemistry. It does meet the criteria for being a destructive device in law.
Calling this "misinformation" is an accurate characterization. You are not responsible for what CNN reports but it should lead you to question the credibility of that news source.
