Tonight's State of the Union address comes at one of the most turbulent times of Donald Trump's second term. In just the past few days, the president's approval rating hit a new low, the Supreme Court struck down his signature economic policy, and now he's sending a massive military buildup to the Middle East while threatening to strike Iran. Whatever he says tonight, Trump warns his speech will be "long," which says a lot considering his last address clocked in at a whopping 99 minutes.
