India, May 29 -- US President Donald Trump has launched a fresh attack on former first lady Jill Biden after she revealed she feared Joe Biden was "having a stroke" during the pair's widely discussed 2024 presidential debate.

In a lengthy Truth Social post, Trump mocked Jill Biden's comments and questioned why she did not intervene during Joe Biden's troubled appearance on stage during the June 2024 showdown in Atlanta.

"Jill Biden is now out there finally admitting that she did NOT know what went wrong with Sleepy Joe during our spectacular, and highly rated, 2024 Presidential Debate," Trump wrote.

Trump's comments came after excerpts from Jill Biden's upcoming memoir and a CBS News interview were reported by US media outlets.
