Congress has authority to make a declaration of war. If Blumenthal really believed his own BS about Russia, he’d introduce a resolution in the Senate for such a declaration and would have Pelosi do the same in the House.
If McConnell knew what he was doing, he would introduce the “Richard Blumenthal Declaration of War on Russia” and put it to a vote. Smoke these vermin out of their holes.
Good suggestion: along same lines as Dem proposal to abolish ICE being brought up for a vote.
