They won't vote for the legislation. Trump told them not to. And the base won't blame them or see any hypocrisy, because it's tied to $ for Ukraine. That's their "reason" and the base is in total agreement that the US shouldn't be funding Ukraine.
Never underestimate the power of right-wing propaganda. We have millions of Americans who now think Putin is a glorious world savior fighting against the evil Nazi Ukrainians.
I am so sick of Republicans bowing down to Donald Trump. He is such a a vile man and yet they have done nothing but put him before the country.
