Breaking News Emails
President Barack Obama made history this week during stops in Asia, and the TSA announced a big leadership change ahead of Memorial Day travel.
Here's a look back at those stories and the week's other top news — in the form of five charts:
1. Obama Makes History in Vietnam, Hiroshima
President Barack Obama called for a world without nuclear weapons on Friday as he became the first sitting U.S. president to visit the site of the Hiroshima atomic bombing. Obama did not apologize for the U.S. actions and instead paid tribute to "all the innocents killed across the arc of that terrible war," saying that "their souls speak to us" and "mere words cannot give voice to such suffering." Earlier in the week, Obama made more history in announcing the lifting of a longstanding arms embargo on Vietnam while visiting the country for the first time.
2. Trump Hits 'Magic Number' of Delegates Required for Nom
Presumptive Republican nominee Donald Trump has officially secured a majority of GOP delegates, giving him the "magic number" required to clinch the GOP nomination. Trump passed the 1,237 mark after unbound delegates from North Dakota, Colorado and Pennsylvania pledged their support for him. NBC News declared the real estate mogul to be the presumptive Republican nominee after his remaining GOP competitors dropped out of the race in early May. Trump will not officially become the nominee until he accepts the nomination at the Republican convention in Cleveland in July.
3. TSA Replaces Head of Security Over Long Airport Lines
The Transportation Security Administration moved dramatically Monday to address the issue of long lines at the nation's airports, replacing its head of security and creating a centralized incident command team at TSA headquarters. Kelly Hoggan, the agency's assistant administrator for security operations since 2013, will be replaced by Darby LaJoye. TSA chief Peter Neffenger — under fire for how his agency has been handling those lines — pledged Wednesday to congressional lawmakers to alleviate the problem, specifically at hard-hit O'Hare International Airport in Chicago.
4. Cosby to Stand Trial in 2004 Sexual Assault Case
The sexual assault case against comedian Bill Cosby will go to trial, a judge decided Tuesday after finding enough evidence in a preliminary hearing to proceed. Montgomery County, Pennsylvania, District Judge Elizabeth McHugh found probable cause after portions of the police statement from accuser Andrea Constand were read in court. Constand was not required to testify and was not in court. Cosby, 78, faces up to 10 years in prison if convicted. The judge's decision marks a stunning turn of events for the once-beloved sitcom star, who thus far had avoided trial.
5. New Taliban Chief Issues Fatwas Justifying Terrorism
The Afghan Taliban confirmed the death of leader Mullah Mansour in a U.S. airstrike and named the group's chief justice — Haibatullah Akhundzada — as his replacement early Wednesday. Akhundzada also served as a judge during the Taliban regime. After the group was routed by the U.S. invasion in 2001, he was made shadow chief justice. Akhundzada, who Taliban sources say is around 60 years old, has issued religious edicts or "fatwas" justifying terrorist attacks against U.S. troops.
