Weeks after he left Rio's 2016 Summer Olympics under a cloud, U.S. swimming star Ryan Lochte is being punished for his behavior in Brazil, which ranged from an altercation at a gas station to making claims that he was robbed — claims that were later deemed to be false.

President Obama repeated his argument that Donald Trump is not qualified to be president.

He urged both voters and journalists to pay careful attention to what he called Trump's "uninformed or outright wacky ideas," and not to grade the Republican White House nominee "on a curve."

"Somehow behavior that in normal times we would consider completely unacceptable and outrageous becomes normalized" during an election campaign, Obama said Thursday at the conclusion of a southeast Asian summit meeting in Laos.

Liberty Media says it has reached an agreement to buy the Formula One auto-racing franchise for $4.4 billion.

As NPR's Yuki Noguchi tells our Newscast unit, the U.S. cable giant "has been on a buying spree, and this acquisition bolsters its sports offerings." Here's more from Yuki:

"Liberty Media is part of the growing media empire controlled by cable-TV pioneer and billionaire John Malone. Malone's properties expanded in the last year to include Time Warner Cable.

Acknowledging that his company has "been slow on this issue," Airbnb CEO and co-founder Brian Chesky is rolling out changes aimed at addressing discrimination complaints against the home rental service. Among the changes: de-emphasizing the role of user photos in arranging stays.

The move comes after longstanding claims from African-American Airbnb customers who said their booking requests were turned down at a high rate.

Rage Against The Busted Medical Machines

"Oh, we have a hematology analyzer but it stopped working," the lab technician said as he pointed to a covered tabletop medical equipment in the corner used to measure blood count levels — an important but simple tool for a community where anemia and infections are prevalent.

Libertarian presidential nominee Gary Johnson asked a television interviewer today, "What is Aleppo?" betraying a lack of interest or even superficial knowledge of the civil war in Syria that's been raging for more than five years.

The question came during an interview on MSNBC's "Morning Joe." Panelist Mike Barnicle asked the two-time libertarian nominee and former governor of New Mexico, "What would you do if you were elected, about Aleppo?"

Air China has apologized for a story in its in-flight magazine that told would-be visitors to London that "precautions are needed when entering areas mainly populated by Indians, Pakistanis and black people."

China's flagship airline has removed copies of the magazine, Wings of China, from its planes, The Associated Press reports. The airline tells the AP it has instructed the magazine's publishers to "strengthen their content review and avoid making similar mistakes."

For many of us, Sept. 11, 2001, is one of those touchstone dates — we remember exactly where we were when we heard that the planes hit the World Trade Center and the Pentagon. I was in Afghanistan.

I'd arrived in Kabul on Sept. 9 to cover the trial of eight foreign aid workers who had been arrested by the Taliban regime, which accused them of preaching Christianity to Afghans. Proselytizing was a death penalty crime, and two Americans were among the accused.

Yosemite National Park is growing by 400 acres — the largest expansion to the park since 1949.

NPR's Nathan Rott reports that the new addition to the park, a stretch of land along the western boundary of Yosemite, has historically been used for logging and cattle grazing.

The Trust for Public Land, a conservation group, bought the land from private owners for $2.3 million and donated it to expand the park. The purchase was supported by the Yosemite Conservancy, National Park Trust and American Rivers, as well as private donors.
