Although it's hard to imagine in light of the Biden administration, there was a time when Democrats were worried about the president's mental health.
During Donald Trump's presidency, Democrats constantly warned that he posed a danger to the country due to his mental instability.
It was said that his erratic actions and jumbled statements demonstrated that he was unable to serve as president.
Some speculated that the Democrats would attempt to remove Trump from office using the 25th Amendment.
Take Speaker Nancy Pelosi as an example (D-CA).
In reaction to several of Trump's tweets on October 8, 2020, Pelosi said that Trump had a "dissociation from reality."
