US President Joe Biden attributed his poor performance in last week's debates with his November election rival, Donald Trump, to fatigue from recent overseas trips, reported AFP. Biden's performance was widely seen as a failure, prompting some in his party to call for the 81-year-old Democrat to step down, although he has shown no intention of leaving the race.

At a campaign rally in Virginia last night, Joe Biden offered a new explanation for his disastrous 90-minute debate against Donald Trump, during which he appeared to lose his train of thought several times, raising concerns about his mental health.

Democrats shocked by Joe Biden's dismal debate performance urged the U.S. president Tuesday to be transparent about his mental fitness as he faced the first call from his own side to drop out of the election.
