I don't know what the actual charges are, I can't seem to find a copy of the criminal complaint. But the DOJ press release included:

"If convicted, the defendant faces a maximum possible sentence of eighty years in prison, followed by three years of supervised release, and a fine of up to $500,000."

She might be charged with terrorism crimes, but either way it looks bad for her. At least a felony - even without prison time that will sting.
