Joe Biden trying to stay positive as he continues campaign trail

US President Joe Biden is trying to stay positive taking his campaign to the battleground state of Pennsylvania. This comes as many have called on him to drop out of the presidential race following his performance against former US President Donald Trump in CNN’s presidential debate. President Biden attended a Sunday church service in Philadelphia during his latest campaign stop. Mr Biden joked about his age and imperfections as he addressed the church to put minds at ease about his capability of running for office.
