HUh? The entire Senate of Democrat members should be recused, as they all have a political reason to vote for conviction. This is nothing but a farce anyway.
Sen Blackburn is simply making a first strike, because the Alinsky Dems will call for recusal of every single ( “biased” ) GOP senator except Romney.
Under the old pre-Trump, pre-Sessions-as-AG politics rules, many GOP would have complied.
