Have you heard the term "not on my watch"?
That's the response from the Senator conducting the Senate trial, I believe, used when he was questioned about the removal of the President from office after the House impeachment of Bill Clinton.
Nobody wanted to be part of that.
In today's political reality, almost nobody wants to be associated with the impeachment of America's first black president.
Senator Sheets Byrd BEFORE the senate hearing on removal of the president. “These may rise to the level of high crimes and misdemeanors, but I’ll not vote to remove.”
