For a second day, thousands of stranded migrants, including refugees from Syria, Afghanistan and Iraq, have camped out at the main train station in Budapest.

As we've reported, the Hungarian government was allowing the migrants to leave without a passport check, but on Tuesday migrants were barred from boarding trains that were headed toward Western Europe.

Reporting from the Keleti Railway Station in Budapest, Joanna Kakissis tells our Newscast unit that the train station has become the latest flashpoint in this migrant crisis. She filed this report:

More adults across the country are strapping on helmets and hopping on bikes to get to work. That's good news for people's hearts and waistlines, but it also means more visits to the emergency room.

Hospital admissions because of bike injuries more than doubled between 1998 and 2013, doctors reported Tuesday in JAMA, the journal of the American Medical Association. And the rise was the biggest with bikers ages 45 and over.

On Wednesday, in honor of footballs that are inflated, we must discuss extra points. The NFL is monkeying around with the extra point again. You think it should? Do you have a better idea? Do we even need an extra point? Why do we have an extra point?

Well, the extra point is vestigial, a leftover from the good old 19th century days when football had identity problems and couldn't decide whether or not it was rugby. Or something. At that point, in fact, what was sort of the extra point counted more than the touchdown itself.

Congress votes on President Obama's nuclear deal with Iran this month. Most lawmakers have said they oppose the deal, yet he has a good chance of winning.

That is because the deal will be considered under rules that favor him, even if only a minority supports him in Congress.

Kentucky's Gov. Steve Beshear says he's powerless to stop Rowan County Clerk Kim Davis from refusing to issue marriage licenses to same-sex couples — something she has done for consecutive days, flouting rulings from federal courts that include the Supreme Court and prompting a motion to hold her in contempt of court.

The federal trial of a Madison Police Department officer accused of using excessive force on an unarmed Indian man began in Huntsville Tuesday.

Madison Police Department officer Eric Parker is charged with violating the civil rights of Sureshbhai Patel, an unarmed 57-year-old Indian man, during a daytime confrontation in February. The encounter was caught on a police cruiser dash cam video. Patel is seen being forcefully swept off his feet and slammed to the ground, causing severe injuries.

The incident sparked an international outcry.

Both the Nasdaq and the Dow Jones index were hit by losses Tuesday, as concerns again rose about China's economy. The Dow is now down nearly 10 percent in 2015, after falling 469 points Tuesday to close at 16,058.

Markets in Europe and Asia also suffered, after renewed worries about a slowdown in China, the world's second-largest economy.

"The latest evidence is China's purchasing manager's index," NPR's John Ydstie reports, "which shows the country's manufacturing sector contracting."

Carly Fiorina was relegated to the JV squad in the Fox News GOP presidential debate in August, but her strong performance that night helped her race past several of her peers in recent polls.

That surge in polling wasn't enough to get her into the next big debate — but it might be now.

That's because CNN Tuesday afternoon changed its criteria for who will get into its main Sept. 16 debate in such a way that Fiorina is much more likely to be included.

More than a month after his trial on murder charges ended in a mistrial for the second time, former Eutawville, S.C., police Chief Richard Combs has been sentenced to a year of home detention. Combs agreed to plead guilty to misconduct in office Tuesday.

Combs, who is white, was the head of the police department in the small town of Eutawville back in May 2011, when he shot and killed 54-year-old Bernard Bailey, who was black, as Bailey tried to drive away from the Eutawville Police Department.

The largest fish farm in America could be built 4 miles off San Diego's coast.

Rose Canyon Fisheries could have a footprint on the ocean floor of 1.3 square miles, about the same size as New York's Central Park. The goal is to produce 11 million pounds of yellowtail and sea bass each year.
