Multiple witnesses subpoenaed in Florida in Trump Mar-a-Lago case

Involvement of top prosecutor Jay Bratt in the Florida grand jury could suggest questions about Espionage Act violations

Federal prosecutors have subpoenaed multiple witnesses to testify before a previously unknown grand jury in Florida in the criminal investigation into Donald Trump's handling of national security materials and obstruction of justice, according to people familiar with the matter.

The new grand jury activity at the US district court in Miami marks the latest twist in the investigation that for months has involved a grand jury that had been taking evidence in the case in Washington but has been silent since the start of last month.
