President Donald Trump has arrived for the G7, or Group of Seven, summit in Canada, a country he's suggested should be annexed, as he wages a trade war with America’s longstanding allies.

If there's a shared mission at this year’s G7 summit, which begins Monday in the Rocky Mountains, it's a desire to minimize any fireworks at a moment of combustible tensions.

Here's the latest:

Sen. Tim Kaine, a Virginia Democrat and a member of the Senate Foreign Relations Committee, is filing a resolution that would require that Congress authorize a declaration of war or any specific use of military force against Iran. Congress passed a similar resolution in 2020 during Trump’s first term.

“It is not in our national security interest to get into a war with Iran unless that war is absolutely necessary to defend the United States. I am deeply concerned that the recent escalation of hostilities between Israel and Iran could quickly pull the United States into another endless conflict,” Kaine said.

The resolution requires that any hostilities with Iran must be explicitly authorized by a declaration of war or specific authorization for use of military force, but would not prevent the United States from defending itself from imminent attack.

The Group of Seven comprises Canada, the United States, France, Italy, Japan, Germany and Britain. Leaders of each nation will be in attendance.

The European Union also attends, as well as other heads of state who are not part of the G7 but have been invited by Carney. These include Ukrainian President Volodymyr Zelenskyy, Mexican President Claudia Sheinbaum, who is expected to have her first in-person meeting with Trump, and Indian Prime Minister Narendra Modi.

Saudi Arabia’s Crown Prince Mohammed bin Salman, the kingdom’s de facto ruler, was invited but will not attend.

Leavenworth, Kansas, occupies a mythic space in American crime, its name alone evoking a short hand for serving hard time. The federal penitentiary housed gangsters Al Capone and Machine Gun Kelly — in a building so storied that it inspired the term “the big house.”

Now Kansas’ oldest city could soon be detaining far less famous people, migrants swept up in President Trump’s promise of mass deportations of those living in the U.S. illegally.

The federal government has signed a deal with the private prison firm CoreCivic Corp. to reopen a 1,033-bed prison in Leavenworth as part of a surge of contracts U.S. Immigration and Customs Enforcement has issued without seeking competitive bids.

ICE has cited a “compelling urgency” for thousands more detention beds, and its efforts have sent profit estimates soaring for politically connected private companies, including CoreCivic, based in the Nashville, Tennessee, area and another giant firm, The Geo Group Inc., headquartered in southern Florida.
