It's interesting that Trump has been all over the Franken thing like flies on sh!t yet he's silent about Roy Moore and about his own accusers. Oh, BTW, where did they all go? Been very quiet.
It's fairly common human behavior to revel in the downfall of your attackers. Roy Moore hasn't spent the last two years reviling Donald Trump, accusing him of being a rapist, and calling him filthy names like Al Franken has, so I'm guessing there's a bit of schadenfreude going on.
Not sure why you find that interesting. Do you also find it interesting that not a single Democrat Congresscritter has denounced Big Al and demanded he resign?
