Oklahoma, Georgia and Washington DC voters head to the polls – US politics live

Hello and welcome to the US politics live blog. Primary elections are taking place in Oklahoma today and a closely watched run-off is underway in Georgia, as Donald Trump’s iron grip on the Republican party faces its next test. In Washington DC - a Democratic stronghold - voters are also selecting a candidate for the party ahead of November’s mayoral election. Oklahoma will hold races to help decide US senate and gubernatorial candidates. Ahead of November’s midterms, president Trump has given his early backing to Kevin Hern in the senate seat previously held by Homeland Security secretary Markwayne Mullin in the deeply conservative state. Hern has kept other potential big challengers at bay in Oklahoma, which hasn’t elected a Democratic senator since 1990, reports AP. But a bigger test of Trump’s influence - which has usually proved potent in Republican primaries this year - may come in a crowded race to succeed outgoing governor Kevin Stitt. In Georgia, meanwhile, Republicans will finalize their selections for gubernatorial and US senate elections. For the senate, US Representative Mike Collins and former University of Tennessee football coach Derek Dooley are the finalists for the Republican nomination. Whoever wins will challenge rising Democratic statr Jon Ossoff for the seat in November. In other developments: The United States and Iran have signed a memo of understanding giving them 60 days to find a way out of the war. The terms of the deal, which has not been publicly released, remain unclear. Vice-president JD Vance called the 1.5-page MOU a “very general document” whose details will be ironed out in the coming weeks of negotiations. The future of the strait of Hormuz remains cloudy. US officials have offered conflicting forecasts for the future of the straight, with Trump saying that by the end of the week it “will be completely open,” while other officials say it may take longer for shipping to return to something approximating the pre-war status quo. Iran foreign ministry spokesperson Esmail Baghei, however, told reporters that Iran may still charge fees to pass through the straight. Trump is in Évian-les-Bains, France, to attend the G7 summit , where Ukrainian president Volodymyr Zelenskyy is hoping world leaders will help him find a way out of his country’s four-year war. He spoke with Donald Trump ahead of the G7 meeting, which Russian leader Vladimir Putin is also attending. California govenor Gavin Newsom is accusing Trump of directing the US justice department to investigate him and his wife. Newsom, a prominent Democrat, tweeted that Trump was coming after him because he is considering running for the president.
