On Monday, US President Joe Biden asserted that he will continue the race of the presidency.
The US President called for the full support from the Democratic lawmakers and party for his presidential campaign.
This call came after the questionable performance for Biden against Trump in the presidential debate and the rise of calls for him to withdraw.
Biden wrote in a letter to the Democrats: "I am firmly committed to staying in the race," adding: "It is time to come together, move forward as a unified party and defeat Donald Trump."
Biden said that he is sure that voters will support him despite the concerns over his age and urged any rivals to challenge him at the upcoming Democratic Party convention.
He told MSNBC's "Morning Joe" television program that he had held several rallies after a disastrous debate performance to "make sure I was right that the average voter out there still wanted Joe Biden, and I'm confident they do."
