It might be hard to believe given the Biden presidency, but at one time, Democrats were allegedly significantly concerned about the mental health of the president of the United States. During Donald Trump’s time at the White House, Democrats claimed he was unstable and a threat to national security. Allegedly, his irrational behavior and incoherent ramblings were proof he couldn’t perform his presidential duties. Rumors began that Democrats would try to use the 25th Amendment to remove him from office.
