The last time I linked to a WaPo article on Chelsea Manning (the last time she was jailed) a mod changed the link so if you find a more informative article you can always post a link and it might be changed.
I don't actually find this to be vastly different in content than the OP but it does seem to give a little more exposition and a little less in terms of boilerplate statements from the attorneys.
Here are some cherry-picked excerpts:
> Manning has offered multiple reasons for refusing to testify, but fundamentally says she considers the whole grand jury process to be unacceptable.
> [The judge] said he hopes that while incarcerated “Ms. Manning would reflect on the principles she says she’s embracing ... and whether those views are worth the price she’s paying for them.”
> Manning herself told the judge directly: “I would rather starve to death than change my principles in this regard.”
