I want you to write to your elected representatives, urging them to deliver more arms and other aid of all kinds, whatever Ukraine asks for, faster and in greater quantities than heretofore provided.
I want you to write to your elected representatives, urging them to impose more and stiffer sanctions on Russia and its trading partners, and signaling to your representatives your willingness to endure some price increases and goods scarcity, if that is what is needed for these sanctions to have teeth.
