After struggling in first debate, Biden's campaign remains resolute, family urges him to stay in the race

Washington — In the wake of President Biden's calamitous debate performance last week, his campaign unveiled a new ad Monday highlighting his more energetic appearances after the debate, in which he called out former President Donald Trump for the many lies and exaggerations he told during the debate. Those post-debate appearances largely took place in front of friendly crowds — much smaller than the 51 million who saw the debate — and in at least two of those appearances, the president read his remarks off a teleprompter. 

After the debate, which has prompted concern among Democrats about President Biden's fitness for a second term, his family is encouraging him to stay in the race and keep fighting, a source with knowledge of the conversations told CBS News. The president was with family on Sunday for a long-planned gathering at Camp David. White House and campaign officials also say there are no plans to make significant changes to the president's campaign schedule or cadence in the wake of the debate. 

Mr. Biden's showing at last week's debate, where the 81-year-old president struggled to correct falsehoods from Trump, while delivering rambling answers to key questions in a hoarse voice, has prompted concerns about his ability to serve and suggestions from some Democrats that he should reconsider his presidential bid. The New York Times editorial board explicitly called on him to drop out of the race. But in the aftermath of the debate, his campaign has said that there are no conversations about the president leaving the race.
