The head of the Transportation Security Administration is heading back to Capitol Hill Wednesday to try to explain what his agency is doing to deal with increasingly long airport security lines that have already snarled the fledgling summer travel season.
TSA Administrator Peter Neffenger is also likely to be pressed by members of the House Homeland Security Committee to explain exactly what prompted the ouster of the agency's top security official, Kelly Hoggan.
Hoggan was removed Monday and replaced by a former federal security director in Los Angeles and New York, Darby LaJoye.
In one of the presidential campaign year's more grisly spectacles, demonstrators at a Donald Trump rally in New Mexico threw burning T-shirts, plastic bottles and other items at police officers, injuring several, and toppled trash cans and barricades. Authorities labeled it a "riot."
Police responded by firing pepper spray and smoke grenades into the crowd outside the Albuquerque Convention Center.
During the rally, the presumptive Republican presidential nominee was interrupted repeatedly by protesters, who shouted, held up banners and resisted removal by security officers.
The banners included the messages "Trump is Fascist" and "We've heard enough."
Meanwhile, Trump added to his list of victories Tuesday with a primary win in Washington state. He ran unopposed after emerging from a crowded field of candidates.
The Afghan Taliban confirmed on Wednesday that their leader Mullah Akhtar Mansour was killed in a U.S. drone strike last week and that they have appointed a successor — a scholar known for extremist views who is unlikely to back a peace process with Kabul.
The announcement came as a suicide bomber struck a minibus carrying court employees in the Afghan capital, killing at least 11 people, an official said. The Taliban promptly claimed responsibility for the attack.
In a statement sent to the media, the Taliban said their new leader is Mullah Haibatullah Akhundzada, one of Mansour's two deputies.
Russia on Wednesday released a military pilot dubbed Ukraine's "Joan of Arc" in an exchange for two Russian prisoners of war, her lawyer said Wednesday, NBC News reported.
Nadiya Savchenko, an Iraq war veteran, was captured by Russians during fighting involving pro-Kremlin rebels in eastern Ukraine in 2014.
She was convicted in March of involvement in the death of two state TV journalists during a shelling. Savchenko, 35, pleaded not guilty, while her lawyers said the case was fabricated by the Russian court.
In Ukraine, she is seen as a symbol of resistance to what most consider an invasion by Vladimir Putin's forces.

Wrapping up a historic visit to Vietnam, President Barack Obama on Wednesday praised the country's next generation of leaders for being more conscious of the environment than previous generations and urged them to "do something about" climate change.
During his final public event here, Obama basked in the admiration of hundreds of young leaders who participated in a town hall-style event and prefaced some of their questions to him with praise about his leadership and his "inspiring speeches."
Obama used a question about preserving a Vietnamese cave from development to pivot to climate change, one of his top issues as president.

Police were readying for the possibility of protests at a Donald Trump rally in Southern California on Wednesday after a similar event drew raucous anti-Trump demonstrations that blocked traffic and damaged police cars.
Authorities have not been informed of any large scale protests but will boost staffing for Trump's noon rally at the 7,500-seat Anaheim Convention Center arena as a precaution, said Anaheim police Sgt. Daron Wyatt.
Last month, anti-Trump demonstrators took to the streets outside a similar event in nearby Costa Mesa, damaging police cars and throwing bottles. At least 17 people were arrested.
Anyone who has been to a nightclub knows bouncers are there to keep people safe, check identification and make the evening peaceful. Some bouncers are expanding their duties by keeping an eye out for terror attacks.
Soft targets, like nightclubs, have been hit by terrorists in places around the world. Robert Smith, a nightclub security consultant, is teaching a group of D.C. club bouncers how they can help protect their establishments and the people inside.
The bouncers are taking a 12-hour class over two days to receive National Host Security Certificate training.
A Pennsylvania mom is speaking out after she says employees at a local YMCA shamed her for breastfeeding her son during a class for toddlers Monday morning.
Kate Haslam, 35, takes her 19-month-old son, West, to a toddler gym class every Monday morning at the Spring Valley YMCA in Limerick, Pennsylvania. This Monday started off just like any other, but little West was hungry, so Haslam sat on a balance beam along the wall in the classroom and breastfed her son.
That's when she says things went downhill. A YMCA employee asked Haslam to leave the classroom and breastfeed outside because she was making people "uncomfortable," Haslam said. When the mom protested, telling the employee it's against the law to tell her to breastfeed elsewhere, Haslam said, two other YMCA officials got involved, pressuring her to move.
Philadelphia Freedom Valley YMCA President & CEO Shaun Elliott, who oversees the Spring Valley YMCA, called the incident a misunderstanding.
Two Democratic senators could be gearing up for an ideological rematch on the best ways to curb sexual assaults in the U.S. military.
Sen. Kirsten Gillibrand of New York said Tuesday she will reintroduce a bill that would remove the decision of whether to prosecute military sexual assaults from the military chain of command — a legislative effort which failed to move forward in 2014 after being opposed by the Pentagon, NBC News reported.
Pushing the bill again may put Gillibrand at odds with Sen. Claire McCaskill of Missouri, who argues that reforming the military from within is the best path to change. She says the Pentagon has made strides in stemming sexual assault in part due to legislation she sponsored that was passed that same year.
But Gillibrand argues that despite attempts at reform, a "troubling command culture" in the military still seems to favor closing cases over pursuing justice.

Toyota said Tuesday it is investing in Uber, making it the latest car company to put money in a ride-hailing app.
The Japanese company did not say how much the investment is worth.
As part of the deal, Uber drivers can lease Toyota vehicles with money earned from their driving.
Investing in ride-hailing services can be a way for automakers to sell more cars. Earlier this year, General Motors Co. invested $500 million in Uber rival Lyft.
A passenger was arrested on a Southwest Airlines flight at Chicago's Midway Airport Tuesday afternoon after allegedly making threatening statements toward a flight attendant, according to the airline.
