 President Trump has not even taken office before critics who considered him dangerous began imagining how to get him out. One idea floated from the very start was the clause of the Constitution permitting the removal of a president deemed unfit to discharge his duties. 25th Amendment to the Constitution, Article 4, David Frum, a conservative author and former speechwriter for President George W. Bush, wrote presciently just eight days after Mr. Trump's election in November 2016. There has been a lot of talk about it.
