Story summary

Iran has warned it will block shipping routes through the Strait of Hormuz that it hasn’t authorized, increasing risks for tankers transporting critical shipments. Last week saw the highest number of attacks on tankers in the region since the start of the conflict with Iran, resulting in a significant decline—more than two months’ lowest—in vessels attempting to navigate through the strait. According to sources close to Tehran, both political leaders and the Revolutionary Guards have agreed on this plan as part of their strategy to maintain control over the strategic waterway. A senior diplomat briefed by Tehran emphasized that Iran plans to use missile, drone attacks, or small boats to intimidate ships away from unauthorized routes, implementing what is described as a "policy of fear and threats."

🔮 Democrats sought on Monday to contain a rift in Michigan's US Senate race after one of their own crossed party lines to endorse the Republican candidate, as both parties made final pitches before midterm elections that will decide control of Congress US Representative Haley Stevens, who lost the Michigan Democrats' Senate primary to Abdul El-Sayed in a bitterly contested race, publicly backed Republican candidate Mike Rogers and appeared with him at a Detroit church, threatening to worsen divisions in a state viewed as crucial to Democratic hopes of retaking the US Senate. The unexpected move lifted the mood of President Donald Trump's Republicans before Tuesday's midterms even as a federal judge dismissed a US Justice Department lawsuit seeking to block certification of election results in Alaska if Republican incumbent Senator Dan S. Sullivan narrowly loses in the battleground state. In Michigan, Stevens' decision to endorse Republican Rogers surprised party leaders, with some members, such as Representative Debbie Dingell, saying that it created a "distraction" for Democrats.
🔮 President Donald Trump’s Justice Department has shown a willingness to intervene directly in Tuesday's midterm elections, breaking with decades of practice meant to avoid the appearance that its law enforcement powers are being used to benefit a political party or candidate.
🔮 US President Donald Trump ordered the agency to write rules that would bar it from delivering ballots if the states did not agree to turn over lists of eligible voters and some voters have expressed concern about voting by mail.
