I see no evidence he was using a metaphor; he spoke it as if it were fact. I’m not giving these smelly animals a break - they lie about everything.

They do lie about everything. They hand us loads of stinky pig crap and call it roses. They’ve been doing that several times a day all during the Bidenrama — about inflation, the border, Trump, insurrection, etc .
