Hello and welcome to the US politics live blog.

New Hampshire and Rhode Island primary voters will choose candidates across a full slate of federal, state and local offices over the next two days.

In New Hampshire, US senator Jeanne Shaheen’s decision to not seek reelection created a cascade of competitive races, AP reported. Two of the eight Republicans hoping to replace the three-term Democrat are former US senators she previously defeated: John E. Sununu and Scott Brown.

The five-way race for the Democratic nomination includes US representative Chris Pappas, whose departure from his 1st congressional district seat in turn attracted a crowd of candidates.

Shaheen’s daughter, Stefany Shaheen, is among those seeking the Democratic nomination for Pappas’ seat, along with former candidate Maura Sullivan. Several other candidates in top races also are making repeat appearances.

Meanwhile, in Rhode Island, governor Dan McKee faces a tough Democratic primary challenge tomorrow in his bid for a second full term. Voters will also choose nominees for a full slate of federal, state and local offices.

McKee was elected governor by a wide margin in 2022 after first assuming the role in March 2021 when then-governor Gina Raimondo stepped down to become US commerce secretary. He now is at risk of becoming the nation’s first elected governor since 2014 to lose renomination and the first in Rhode Island since 1994.

His challenger is Helena Buonanno Foulkes, a former longtime executive with Rhode Island-based CVS. She placed a close second behind McKee in the five-way 2022 Democratic primary. She is the niece of former Democratic senator Chris Dodd of Connecticut.

• President Donald Trump said on Monday that ⁠Canadian private jet maker Bombardier would ⁠no longer be allowed ​to sell its planes in the United States unless it started manufacturing in the country. “NO MORE SELLING BOMBARDIER IN THE UNITED STATES! Their products aren’t good enough!” Trump said in a post on Truth Social. “If ⁠they want our Market, they must build here, and stop treating America like a ’piggybank’.”

• New York mayor Zohran Mamdani is set to come face-to-face with Rudy Giuliani at the main September 11 memorial service, just days after the former mayor – who led the city at the time of the 2001 terrorist attacks – disparaged his Muslim religion and said he should skip the ceremony. In an interview with right-leaning Newsmax at the weekend, Giuliani said: “Having lost friends there and being very close to many of the families, it offends me that he’s coming.”

• A cluster of advocacy groups that boast veteran lawyers, voting experts and ex-judges have expanded legal challenges to Donald Trump’s authoritarian executive orders on voting and other presidential actions they see as a “war” on the rule of law in the US. Heavy legal opposition to Trump’s two executive orders on elections to curb voting rights and supplant the authority of states on election matters has come from the Democracy Defenders Fund, the Campaign Legal Center, the American Civil Liberties Union and kindred groups.

• The US Department of Health and Human Services (HHS) recently released a report linking “gender ideology” to leftwing authoritarianism and political violence – a study scientists say was poorly conducted and “nakedly political”, likely leading to greater politicization of science and health. It follows attempts by the administration to limit access to gender-affirming care – including, on Friday, an agreement reached between the Department of Justice and a New York hospital to no longer offer pediatric gender-affirming care.
