Donald Trump claimed Sunday that Nancy Pelosi is not fit to serve as questions over her status as third-in-line to the presidency emerge after she formed a commission on removing from office presidents deemed unfit.'I don't think she could pass basic aptitude test personally,' Trump told Fox News Sunday morning. 'I really don't, I don't believe it.'The comments come as concerns from conservatives arise over the fact Pelosi could rise to power in the case of a contested election.On Friday, Pelosi rolled out legislation to set up a commission under the 25th Amendment to weigh whether a president is incapacitated.She claimed the move had nothing to do with potentially removing COVID-19-stricken President Donald Trump and having Vice President Mike Pence take over.

The Dems want that to happen fast because Sleepy Joe is out of it!!!' Trump tweeted Friday.Pelosi heavily hyped the upcoming legislative move on Thursday but when she unveiled the plan, immediately made clear it was in effect a troll against the president.'This is not about president Trump. He will face the judgement of the voters,' Pelosi told reporters in a press conference at the Capitol.'He shows the need for us to create a process for future presidents,' she said.Pelosi faced repeated questions about her intentions as she noted a day earlier that the president was medicated and questioned his 'capacity' in a letter to co
