A Reuters review published September 21, 2026 found that “Since January 1, Trump has called out Biden by name at least 890 times, spanning almost 200 events and interviews and around 190 Truth Social posts this year.” That is his predecessor as a target “on average three times a day.” By subject, “He invoked Biden at least 210 times on the economy, 168 times on immigration and 138 times on foreign policy and national security matters,” including at least 37 times about the Iran war Trump started in February. Reuters notes that Biden, now 83 and battling Stage 4 cancer, “has largely withdrawn from public life.” The count is Reuters' own analysis of Trump's public remarks and posts since January.
The pattern is sharpest on prices. “In February, Trump told an interviewer he owned the economy,” Reuters reports; by September he was posting, “I hope everyone realizes that price increases throughout America were caused by Sleepy Joe Biden and the Biden Administration, not by 'TRUMP.'” Reuters sets the record beside the claim: “Averaging 4.95% a month during Biden's four years, year-on-year inflation has averaged 2.94% a month since Trump took office and stood at 3.4% last month.” On weapons, after his own war drew down U.S. stockpiles, he said on July 27, “I'd like to have more (munitions) to be honest, but so much was given to Ukraine by Biden.” At the Republican midterm convention in Dallas on September 9, he said Democrats “delivered you four years of disaster, bedlam and death under sleepy Joe Biden.” On immigration he has acknowledged his staff wants him to move on: “Even my speechwriters, they say, 'Sir, nobody wants to hear about the border anymore. You've done it.'”
White House spokeswoman Olivia Wales defended it: “Joe Biden is the worst president in American history, and President Trump has spent every day cleaning up his mess and making the United States of America stronger than ever before.” Republican strategists were less sure. Ryan Williams said, “Donald Trump always needs a foil and it's better to have a single person than a party,” and veteran strategist Charlie Black, who has sometimes criticized Trump, said, “blaming your predecessor does not work. Especially for an incumbent. He must defend his own record to help his party.” Former Biden aide Meghan Hays: “Nine hundred mentions in less than a year isn't governing, it's an obsession.”
