US President Joe Biden explained his failed debates last week with his rival in the November election Donald Trump with fatigue, accumulated from recent visits abroad, reported France Press, quoted by BTA.
Biden's run was seen by many as a failure, and while the president has given no indication that he intends to leave the race and has been defended by some in his own party, there have been calls for the 81-year-old Democrat to step down. Last month, Biden visited France and Italy.
At a meeting with his party's donors near Washington, the US president admitted that it was not "very smart" on his part "to travel several times around the world" shortly before facing Trump. "I didn't listen to my advisors" and "almost fell asleep" during the debates, he confided.
Biden emphasized that "this is not an apology, but an explanation".
US Vice President Kamala Harris, meanwhile, has again backed the head of state, amid calls for him to step down and at a time when she is among the Democratic Party's mentioned possible candidates.
"I'm proud" to be in tandem with Joe Biden in the November election. He "is our candidate," Harris told CBS News. "We have already defeated Donald Trump once and we will defeat him again,", she expressed confidence.
