Mullin refused to comment, however, on a shooting in Maine and other deadly encounters with Immigration and Customs Enforcement, which have raised questions about how ICE officers are vetted. The officer involved in the Maine killing had a history of mental health issues and violent behavior, the AP reported Thursday. Mullin said the shooting was being investigated. Trump’s speech elevated his yearslong push to raise doubts about the legitimacy of U.S. elections and dispute his 2020 loss to justify his push to pass a strict voter ID bill. His allegations of interference focused on China but lacked key context and evidence that votes or the election outcome were manipulated. Trump also said he was releasing previously classified documents related to the 2020 and 2018 elections. The president’s return to the subject comes despite persistent voter concerns about the cost of living and U.S. forces escalating strikes on Iran in a conflict for which there is no end in sight.
