Indiana expanded Medicaid under the Affordable Care Act in 2015, with a few extra conditions that were designed to appeal to the conservative leadership in the state. The Federal government approved the experiment, called the Healthy Indiana Plan, or HIP 2.0, and it is now is up for another three-year renewal.

On the eve of the vote for the next chair of the Democratic National Committee, the crowded field is thinning out.

South Carolina Democratic Chair Jaime Harrison dropped out of the race Thursday and endorsed former Labor Secretary Tom Perez. The move comes days after another candidate, New Hampshire Democratic Chair Ray Buckley, exited the race and threw his support to Rep. Keith Ellison of Minnesota.

In the cavernous basement of St. Thomas Aquinas community center in South Philadelphia, a mock immigration raid is underway.

As one woman yells "Help! Help!" — pretending to be taken by federal immigration officers — volunteers being trained to disrupt a raid begin singing and sit down as one, blocking the officers' path.

Malaysian authorities say initial autopsy results show a chemical weapon — VX nerve agent — was used in the fatal poisoning of Kim Jong Nam, older half-brother of North Korea's leader Kim Jong Un.

VX is an odorless substance that can exist as liquid or gas. It can kill within minutes if it's passed through the skin. It is 10 times more toxic than sarin and classified as a weapon of mass destruction.

Some students, principals, parents and attorneys have condemned the Trump administration's decision to remove some federal protections for transgender students.

Those protections had been issued by President Barack Obama, who cited the federal Title IX law, and instructed public schools last year to allow transgender students to use restrooms and locker rooms that match their gender identities.

The war against ISIS is entering a tough new phase, as Iraqi fighters with growing U.S. assistance push into western Mosul, warns the senior American commander in Iraq, Lt. Gen. Stephen J. Townsend.

"ISIS is a brutal, brutal enemy," said Townsend, speaking in Erbil as Iraq's security forces were about to attack Mosul's airport with help from the U.S.-led anti-ISIS coalition.

President Trump has promised to build a wall along the 2,000 miles of the U.S.-Mexico border.

A third of that border already has a barrier, thanks to the Secure Fence Act of 2006, which was signed by then-President George W. Bush. That initiative ran into issues with landowners near the Rio Grande. If the wall goes forward as Trump promises, more lawsuits may be coming.

In America, there is a rare echelon of pop stars so big they only need one name: Madonna, Cher, Prince. In Italy, that name is Zucchero.

This week United Nations officials declared that a famine in South Sudan is growing — fueled by a deadly combination of drought and conflict. They estimate that nearly 4 million people are already struggling to get enough food. And officials expect the famine will spread to more areas in the coming months affecting an additional 1 million people.

Meanwhile the threat of famine is looming over three other countries: Nigeria, Somalia and Yemen, putting a total of 1.4 million children at risk of death this year.

At a joint news conference in Mexico City on Thursday, Secretary of State Rex Tillerson acknowledged the tension between the U.S. and Mexico. After talks with his Mexican counterpart, Foreign Minister Luis Videgaray, Tillerson said that "in a relationship filled with vibrant colors, two strong sovereign countries, from time to time, will have differences."

The oft-overlooked Oscar category of best documentary short has a dramatic theme this year: Three of the five films nominated are about Syrians, and each offers an intimate, eye-witness account of the devastation in that country.

One of the shorts, The White Helmets, follows a group of civilian volunteers in Aleppo who search for and rescue bombing victims. They're the only first responders left and they've saved tens of thousands of people, digging them out from the rubble. (The sound of bombs blasting can be heard throughout the film.)

Murders are on the rise in the United States.

The national murder rate jumped dramatically in 2015, and early indications are that it rose again in 2016, though official numbers aren't available yet.

Amid deep strains in the U.S. relationship with Mexico, a country that's been a favorite target of President Trump, Secretary of State Rex Tillerson and Homeland Security chief John Kelly took part in talks in Mexico City on Thursday that were aimed at smoothing out tensions.

"That's going to be a tough trip," the president said Thursday morning at the White House. Some of the key issues between the two countries: immigration, border security, trade and U.S. aid to Mexico.

Lawyers for a 17-year-old transgender student and the Gloucester, Va., school board that wants to limit which bathroom he can use don't agree on much.

But both sides have concluded the Trump administration's decision this week to revoke guidance that protects transgender students' ability to use bathrooms and locker rooms that correspond with their gender identity only heightens the need for a hearing before the nation's highest court.

Russian Defense Minister Sergei Shoigu made his way to the Duma, the lower house of parliament, on the eve of Defender of the Fatherland Day. The Feb. 23 national holiday was once known as Soviet Army and Navy Day, and Shoigu, dressed in the uniform of a general, came to boast about the Russian military's latest achievements.

"We tested 162 types of contemporary and modernized weapons in Syria, which showed a high level of effectiveness," Shoigu said. Only 10 weapons systems performed below expectations, he added.
