Adjourned [UPDATED]
The grand jury has adjourned after meeting for 3 hours. No word on what they did or didn't do. If the previous rumors about a filing today and an announcement tomorrow do not pan out, then there's no reason to think these sources are as good as we've hoped and no reason to think anyone has the slightest clue what's happened or is going to happen. But, assuming that info was good, Raw Story's offering today makes plenty of sense as to what we may expect:

Special Prosecutor Patrick J. Fitzgerald has asked the grand jury investigating the outing of CIA operative Valerie Plame Wilson to indict Vice President Dick Cheney’s chief of staff I. Lewis “Scooter” Libby and Bush’s Deputy Chief of Staff Karl Rove on charges of perjury and obstruction of justice, lawyers close to the investigation tell RAW STORY.

Fitzgerald has also asked the jury to indict Libby on a second charge: knowingly outing a covert operative, the lawyers said. They said the prosecutor believes that Libby violated a 1982 law that made it illegal to unmask an undercover CIA agent.

That report also says that indictment of 2 additional figures not in the White House is being sought as well, and that Karl Rove has turned down an offer to plead guilty on perjury to avoid facing charges of obstruction. I guess we'll see.

[UPDATE 2:20 central--Richard Sale reports that yesterday's rumors are still operative. Indictments today; press conference tomorrow.]
