1. President Trump called off peace talks with the Taliban, ending monthslong negotiations that had appeared to be nearing an agreement.

Mr. Trump cited a suicide bombing last week that killed a U.S. soldier and 11 others in Kabul as he tweeted that he had canceled a secret meeting at Camp David with Taliban leaders and the Afghan president. But officials who spoke to our reporters say it had more to do with the Taliban’s resistance to the U.S. terms, and the rushed plan for a Camp David summit.

Separately, when Congress returns from its summer recess on Monday, Democrats plan to scrutinize whether Mr. Trump’s resort properties illegally profited from government business. Patronizing Trump hotels is an almost routine part of doing business in Washington. Hundreds of officials have done so.
