The Senate Foreign Relations Committee announced it will host Secretary of Defense Jim Mattis and Secretary of State Rex Tillerson for a public hearing about passing a new authorization for use of military force (AUMF). Presidents Bush, Obama and Trump have all used a broad 2001 AUMF to justify military actions in Iraq, Afghanistan and elsewhere.

After Mattis and Tillerson participated in a closed-door session with senators this August, Senator Tim Kaine said they "did not specifically reject" a new AUMF. Rand Paul's proposal to repeal the 2001 AUMF was shot down by a 61-36 vote.

Be smart: Senator Chris Murphy, who sits on the committee, views passing a new AUMF as a way to signal to Trump he can't take action on North Korea without congressional approval.

Senator Tim Kaine said in a statement that the "questions surrounding the death of American service members in Niger show the urgent need to have a public discussion about the current extent of our military operations around the world," and said he thinks a new AUMF can be better formulated to address non-state actors.

Islamic State claims responsibility for deadly bombing in southern Afghanistan

The Islamic State group claimed responsibility for a massive blast that tore through a crowded Shiite mosque in the southern Afghan city of Kandahar on Friday, killing at least 47 people and injuring dozens more, AP reports.

Why it matters: Friday's attack was the deadliest to strike Afghanistan since the U.S. withdrew its troops from the region and is the second major attack on a Shiite mosque in a week, underscoring the Taliban's growing security threat from other militant groups.

New wave of strikes will test worker power

Thousands of John Deere workers hit the picket line this week after the union smacked down a new worker contract from the farm and equipment maker.

Why it matters: There’s a wave of worker angst spreading across the country. They wield new power that’s come with a historic worker shortage.

Better sensors, more intelligent AI, and the coming wave of 5G wireless could finally fulfill the promise of the smart city.

Why it matters: How we organize, run and power our cities will be increasingly important in the years ahead, as urbanization expands and the damaging effects of climate change compound.
