Search warrant: Twitler investigated under Espionage Act

The report from Politico:

"The warrant shows federal law enforcement was investigating Trump for removal or destruction of records, obstruction of justice and violating the Espionage Act — which can encompass crimes beyond spying, such as the refusal to return national security documents upon request. Conviction under the statutes can result in imprisonment or fines. [...] A receipt accompanying the search warrant, viewed by POLITICO in advance of its unsealing, shows that Trump possessed 'documents marked with TS/SCI [top secret/sensitive compartmented information].'"

As to what was in those documents was not disclosed by the warrant. However WaPo earlier reported that some of them related to nuclear weapons, which is consistent with the Espionage Act and the TS/SCI rating.
