WILLIAM BRANGHAM: Good evening.

I'm William Brangham.

John Yang is away.

We begin tonight with dueling rulings from two federal judges that threatens access to the most commonly used method of abortion in this country.

The drug in question is mifepristone, which was approved for use by the Food and Drug Administration in 2000.

Friday night a federal judge in Texas appointed by President Trump put a hold on that drugs ongoing approval while a lawsuit questioning its safety continues.

Separately, a judge in Washington State appointed by President Obama ordered U.S. authorities not to make changes that would restrict access to the drug.

President Biden condemned the Texas ruling and the Department of Justice has filed an appeal.

We'll take a closer look at these rulings and what they mean later in the program.

The Justice Department has launched an investigation into the potential leak of Pentagon documents that detail U.S. and NATO aid to Ukraine.

The documents labeled secret were posted on social media sites.

They appear to be routine updates and dispatches, though some may have been altered.

This comes as the New York Times and others report, more documents have begun to appear online, allegedly revealing the depth of U.S. intelligence on Russia's war plans and how the U.S. is spying on allies to track the war.

Tensions between Taiwan and China rose today as the Chinese military sent warships and fighter jets closer to Taiwan.

Chinese state television released footage of the drills which are supposed to last for three days.

Taiwan's defense ministry said it spotted 71 Chinese aircraft, including fighter jets and bombers crossing an unofficial barrier between the two countries.

Beijing views Taiwan as part of China.

These exercises come after Wednesday's meeting in Los Angeles, between House Speaker Kevin McCarthy and Taiwan's President Tsai Ing-wen.

Police in Iran today announced they've started installing cameras in public locations to identify women who don't wear their veils.

Official say once identified the women will receive a text message detailing the consequences of not covering their hair.

It is the latest effort to crack down on resistance to Iran hijab law, a dress code imposed after the 1979 revolution.

Since last fall, more Iranian women have been taking off their veils to protest the death of Mahsa Amini, a Kurdish woman who died in police custody after being held for allegedly violating the hijab rule.
