Donald Trump indicted for second time, in classified documents investigation - Blåhaj Lemmy

What does "indicted" mean exactly?
Formally accused
what's the difference between formal accusation and informal one?
Another fun bit, they're federal charges. Which 97% of the time lead to convictions. Feds don't fuck around, they don't leave much room for error. Now the question is whether he spends time behind bars. 37 counts on the indictment is a lot and I hope he rots in jail.
