U.S. stock futures rose after President Donald Trump extended a deadline to attack Iran's energy infrastructure to April 6, a week after the original deadline was set to end. The Dow Jones Industrial Average futures rose by 92 points, or 0.2%, and S&P 500 futures and Nasdaq 100 futures each rose by 0.3%. The extension is part of ongoing negotiations with Iran regarding an end to the U.S.-Iran war, which has resulted in rising oil prices and could impact voters at the pump and Republicans' seats in the midterms. However, uncertainty remains over Iran's intentions to engage in talks with the US.
