US President Joe Biden is drawing a lot of criticism over his performance at the presidential debate against his rival Donald Trump. Media and political analysts have raised several questions over Biden's fitness.
Amid this, there are speculations that former First Lady Michelle Obama might replace him as the Democratic nominee in the presidential election that are set to held in November.
US Senator and Republican leader Ted Cruz said the change would occur at the Democratic National Convention in August.
However, former President Barack Obama has backed Biden saying bad debate nights happen.
Obama said that this election is still a choice between someone who has fought for ordinary folks his entire life and someone who only cares about himself.
