AMNA NAWAZ: In the day's other headlines: The container ship that caused the deadly bridge collapse in Baltimore has finally returned to port.

Its bow is still covered in damaged containers, steel and concrete.

Port officials said today they're getting closer to fully reopening the channel.

JONATHAN DANIELS, Executive Director, Maryland Port Administration: So, as far as the depth and the draft that's necessary to bring the larger vessels in, that depth is there.

We just don't have the width.

There's still material, there's still bridge sections that are in place.

But as the Army Corps and the unified command has indicated, they're looking at the end of May.

AMNA NAWAZ: In the meantime, shipping company officials are working on allowing the ship's 21 crew members to disembark.

They'd stayed on board for maintenance and to help investigators determine what led to the crash.

The United States remains determined to do our part.

Speaking to Reuters News Agency, he said that for, every one big step forward, there are two steps back.

A British court has ruled that WikiLeaks founder Julian Assange can challenge his extradition to the U.S. His lawyers had argued that his free speech rights would not be protected if he was sent here to face trial.

Supporters outside the court celebrated the decision.

His wife, Stella, called for U.S. authorities to drop the charges.

STELLA ASSANGE, Wife of Julian Assange: As a family, we are relieved, but how long can this go on?
