President Donald Trump called former President Barack Obama a 'rotten president' at a rally in Park City, Kansas, on Monday, 19 October 2026. He repeatedly used 'testifying' while discussing Obama's support for Michigan Democratic U.S. Senate candidate Abdul El-Sayed. Trump later said Obama was going to help El-Sayed campaign.
For context, Trump was campaigning near Wichita for Republican Sen. Roger Marshall of Kansas, just over two weeks before the 03 November 2026 midterm elections. El-Sayed's campaign had already announced Obama's endorsement and an appearance in Detroit, scheduled for 24 October 2026.
