Rep. Thomas Massie of Kentucky lost the Republican primary for his House seat by nearly 10 percentage points on Tuesday. Trump-endorsed challenger Ed Gallrein defeated Massie, who becomes the latest Republican incumbent to lose after drawing opposition from the president. The race set a record for spending in a House primary, with $33 million spent on television advertisements, the majority directed against Massie, according to data from NPR's ad-tracking partner AdImpact. In Georgia and other states, Democratic primary participation remained elevated, which some analysts view as an indicator of potential turnout in the November midterm elections. Four main observations emerged from the night's contests.

Several U.S. House primaries in Alabama will not be decided immediately and will instead require special elections later because of court-ordered redistricting. The state is returning certain districts to previous boundaries that historically favored Republican candidates. In numerous other races nationwide, the general election outcome was effectively settled on Tuesday because the contests lacked major-party opposition, NPR's Stephen Fowler reported. Former Atlanta Mayor Keisha Lance Bottoms won the Democratic primary for Georgia governor. She will face the winner of the Republican runoff between Lt. Gov. Burt Jones and healthcare executive Rick Jackson, scheduled for next month.

President Trump stated that he was approximately one hour from ordering additional military strikes on Iran before halting the plans. He attributed the delay to ongoing negotiations and indicated he would allow Iran two or three days, or possibly up to a week, to reach an agreement. Vice President Vance described the situation as presenting Iran with two paths: continued talks or resumption of military action.

The prospect of renewed U.S. strikes this weekend underscores the unpredictability that some analysts believe could extend the current conflict. Mona Yacoubian, a former State Department official now at the Center for Strategic and International Studies, noted the risk that the situation could settle into a prolonged standoff capable of renewed escalation. Vance has described Iranian leadership as divided, with differing views on next steps. He said it remains unclear whether the divisions result from communication failures or differing intentions, but he noted that such divisions complicate efforts to reach an accord.

San Diego police have provided additional information on the victims and the two suspects in the attack at a California mosque that left five people dead. Police Chief Scott Wahl said the three civilian victims were killed while attempting to intervene against the gunmen. Imam Taha Hassane of the Islamic Center of San Diego identified the victims as Mansour Kaziha, 78, Nader Awad, 57, and Amin Abdullah, 51. Officials reported that Abdullah, who worked as a security guard at the site, shielded approximately 140 children during the incident. The two teenage suspects had met online. An FBI special agent stated that the suspects "did not discriminate on who they hated."

The suspects appear to have livestreamed the attack. A 75-page document attributed to them has been reviewed by investigators. NPR confirmed the names of two individuals referenced in the document with a person familiar with the case who was not authorized to comment publicly. The writings and video indicate that the suspects participated in an online white supremacist accelerationist network, according to NPR extremism correspondent Odette Yousef. Elements of the attack, including the livestream format and the clothing worn by the suspects, parallel aspects of the 2019 mosque shootings in Christchurch, New Zealand. The document referenced concerns about Sharia law in small Texas towns and allegations of fraud involving Somali-run daycares in Minnesota. Investigators continue to examine the online materials and communications associated with the suspects.

Minnesota Gov. Tim Walz signed legislation that prohibits the operation of prediction-market platforms within the state. The Trump administration has filed a lawsuit challenging the measure. The law defines prediction markets as systems permitting wagers on future events, including elections, sports, entertainment, and international developments. Platforms that continue to offer services in Minnesota could face felony charges once the statute takes effect in August.

NPR is devoting a week to reporting on local and regional efforts to reduce greenhouse-gas emissions and prepare for extreme weather, even as federal climate initiatives have been scaled back. Denver's largest source of emissions stems from energy use in commercial buildings. The city operates the nation's oldest continuously running commercial steam system, which supplies heat to more than 100 downtown structures and relies on natural gas combustion. City officials are now developing a thermal energy network that would use water circulated through underground pipes, geothermal sources, and waste heat from sewage to heat and cool a group of 11 municipally owned buildings. The project aims to convert portions of the existing steam infrastructure into an ambient loop over the next decade. Comparable systems already operate in other cities and on university campuses. If the Denver pilot succeeds, it could serve as a model for other dense urban districts seeking to lower building-related emissions.

Cambria CEO Marty Davis, a donor to President Trump, has petitioned federal agencies multiple times for tariffs on imported quartz used in countertops. Davis's company, valued at approximately $500 million, produces quartz slabs domestically. Competitors contend that the tariffs raise input costs for firms that import materials, resulting in higher prices passed on to consumers. They argue the measures disproportionately affect smaller businesses and middle-income homeowners.

In 2018, during Trump's first term, Cambria obtained tariffs on quartz imported from China through a petition to the U.S. International Trade Commission. The company later sought similar duties on imports from India and Turkey. In September 2025, Cambria and other domestic producers requested a global safeguard investigation into a reported surge in imports and alleged tariff circumvention. In April, the commission recommended tariffs of up to 40 percent on imported quartz slabs for four years, along with import quotas. The final decision rests with the president.

A recent study found that widening gaps in educational attainment and earnings between men and women are altering marriage and family patterns, reducing the number of financially stable male partners available to some women. Autumn Barnes recalled that her mother, Barb Barnes, had difficulty discontinuing opioid medication prescribed after open-heart surgery in 2005. A nurse who had overcome similar dependence provided guidance that helped Barb manage pain without long-term reliance on the drugs. A coalition of 24 states and the District of Columbia sued the Trump administration over a new rule that restricts federal student-loan eligibility for borrowers enrolled in certain graduate healthcare programs.
