U.S. President Donald Trump's impeachment trial, which begins next week, may pose one of the greatest political challenges
Senate Majority Leader Mitch McConnell has faced in more than three decades in Congress.
McConnell, the top
Republican in
Congress, says America's founders created the Senate for moments such as this, to block the "factional fevers" and "runaway passions" of the House of Representatives.
The reserved Senate leader, who represents Trump-friendly Kentucky, views with contempt the allegations by the Democratic-controlled House that the Republican president abused his power.
