"Trump Continues to Confuse Biden and Obama in Campaign Speeches"

During a rally in Virginia, Donald Trump mistakenly referred to Barack Obama as the current president, adding to concerns about the age of both Trump and Joe Biden, who are the oldest presidential candidates in US history. Biden also recently confused Gaza with Ukraine while discussing aid efforts. Questions about their age and cognitive abilities have intensified, with a majority of voters expressing concerns about Biden's age.
