She has an excellent article that is well-worth reading in full but I will give you a few paragraphs to whet your appetite.

The Espionage Act was crafted in 1917 — because President Woodrow Wilson wanted a war and, faced with the troublesome First Amendment, wished to criminalize speech critical of his war. In the run-up to World War One, there were many ordinary citizens — educators, journalists, publishers, civil rights leaders, union activists — who were speaking out against US involvement in the war.

If Assange can be prosecuted under the Espionage Act, then so can the New York Times; and the producers of Parker Spitzer, who discussed the WikiLeaks material two nights ago; and the people who posted a mirror WikiLeaks site on my Facebook ‘fan’ page; and Fox News producers, who addressed the leak and summarized the content of the classified information; and every one of you who may have downloaded information about it; and so on. That is why prosecution via the Espionage Act is so dangerous — not for Assange alone, but for every one of us, regardless of our political views.

She calls on people to demand the repeal of the Espionage Act.
