Mitch McConnell and the vast majority of Republican Congresspeople have announced that they will refuse to consider any Supreme Court candidate proposed by President Obama. Treason is defined as "The act of betraying one's country", and in the past eight years, Mitch McConnell, along with much of the republican party have done just that by repeatedly obstructing and obfuscating progress and intentionally sabotaging any policy put in place by President Obama, purely for partisan reasons.
By doing so, Mitch McConnell and Republican leaders have committed treason against America and must be held accountable for their actions.
