Thank you for speaking up for Ukraine. Now please do something

I am alarmed by Trump impounding support for Ukraine and now by stopping sharing military intelligence. This gives aid and succor to Russia and will cause deaths in Ukraine. It looks as if Trump is Putin's tool. European leaders have been making this very point in public. Thank you for making this statement: "I do not think we should be pausing our efforts. It’s the Ukrainians who are shedding blood,” Senator Collins said, calling the current moment “a critical time for Ukraine.” Yes, it is indeed a critical moment. Please back up your words with meaningful action. Surely you realise that in this critical moment, fine words, concern and disappointment count for zero. Perhaps they accomplish something by showing your colleagues where you stand. As appropriations chair, you have tools: you can use subpoena power, call witnesses for questions, make criminal and judicial referrals and speak out with more vehemence and moral clarity. Please take more forceful and effective action now. Failure to act gives more succour to our foe, Russia. Surely that is not what you intend? It's been widely reported that GOP members of Congress are being pusillanimous Trump-appeasers, scared to speak out, because Trump makes threats against them. Consider please that Ukraine's soldiers have their lives on the line. Find your courage and do something effective. Words are not enough at a critical moment. Do more now. Please reply to let me know what you will do.
