President Biden pointedly explored attacking former President Trump over his age in an interview on NBC's "Late Night." Biden, who is 81, joked that while he and Trump are around the same age, "he can't remember his wife's name," referencing a recent gaffe. Biden said voters should consider candidates' ideas and that Trump "wants to take us back" on issues like abortion that have been settled for decades. Biden's comments mark a shift and come after Trump's win in the South Carolina primary, putting him on track for the 2024 nomination. Biden plans a border visit on the same day as Trump and will meet congressional leaders to discuss border issues and other priorities.
