The headline here is a direct quote of the headline DOJ gave to a U.S. Justice Department press release dated May 7, 2021; (which links to online copies of the actual Indictments filed in court).
While news of federal charges to be filed was leaked prior to May 7, that is the date when news outlets had actual notice of filing and of content of Indictments.
MinnPost reported of the federal charges today, May 27, 2021. Crabgrass knows of no earlier online press reporting in such detail with links to Indictment texts as filed. (MinnPost did not give the DOJ press release link). Other outlets might have reported earlier on indictment detail, but the MinnPost item is where Crabgrass first noted that federal indictments had been filed, and what filed documents reportedly said.
Crabgrass posts this notice, in case readers were unaware of indictment detail.
