A portrait of former US President Ronald Reagan hangs behind US President Donald Trump as Trump makes an announcement on prescription drugs in the Oval Office of the White House in Washington, DC, on September 30, 2025. Trump on Tuesday announced a deal with the pharmaceutical giant Pfizer that he said would lower certain drug prices in the United States, without providing specifics. The US president, flanked by top officials, was scant on details but indicated the deal involves granting the company a three-year reprieve on planned pharmaceutical tariffs. The announcement saw Pfizer's stock price rise by five percent. (Photo by Brendan SMIALOWSKI / AFP)
