The Biden administration has been saying all the right things lately about respecting a free and vigorous press, after four years of relentless media-bashing and legal assaults under Donald Trump.

The attorney general, Merrick Garland, has even put in place expanded protections for journalists this fall, saying that "a free and independent press is vital to the functioning of our democracy".

But the biggest test of Biden's commitment remains imprisoned in a jail cell in London, where WikiLeaks founder Julian Assange has been held since 2019 while facing prosecution in the United States under the Espionage Act, a century-old statute that has never been used before for publishing classified information.

Whether the US justice department continues to pursue the Trump-era charges against the notorious leaker, whose group put out secret information on the wars in Iraq and Afghanistan, Guantánamo Bay, American diplomacy and internal Democratic politics before the 2016 election, will go a long way toward determining whether the current administration intends to make good on its pledges to protect the press.

Now Biden is facing a re-energized push, both inside the United States and overseas, to drop Assange's protracted prosecution.

Five major media organizations that relied on his trove of government secrets, including the Guardian and the New York Times, put out an open letter earlier this month saying that his indictment "sets a dangerous precedent" and threatens to undermine the first amendment.
