US President Joe Biden acknowledged what has been dubbed as a disastrous performance during the first presidential debate with Donald Trump. Biden promised to “get back up” while addressing a campaign rally in North Carolina on June 28. He said that he intended to defeat Republican rival Donald Trump in the November presidential election. “Folks, let me close with this. I know I’m not a young man, to state the obvious. Well, I know. I don’t walk as easily as I used to. I don’t speak as smoothly as I used to. I don’t debate as well as I used to”, Biden said at a campaign rally in North Carolina a day after the first presidential debate. Biden’s appearance at a campaign rally in North Carolina came amid criticism that he should step aside and let another candidate run for the president’s post.
