Can someone explain?

[u/cutieeblondee2000]

so i’m not too savvy when it comes to knowledge about American courthouses etc (originally from the UK) and just wanted to know if someone could explain this to me? It says he is set to appear in federal court on January 18th and could return ‘if prosecutors don’t get a grand jury indictment’ but then says his next scheduled appearance is February 21st. What exactly is happening on these two dates? Would appreciate any help on this. I am also hoping to go to the trial if it is open to the public so also trying to figure out what date that is. thanks friends!!
