Graham said that the Ukrainian military needs tanks.
"Why don't you call for tanks to be sent to our southern border where the country is being invaded every day and Americans are being killed in record numbers with fentanyl," Green tweeted in response to Graham's call.
She recalled that US lawmakers serve the American people, not Ukrainian President Volodymyr Zelensky.
Earlier, retired American Lieutenant Colonel Daniel Davis said that Abrams and Leopard tanks, even if delivered to Ukraine, would not help the Ukrainian army turn the tide of hostilities and defeat the Russian Armed Forces.
