The argument began after Crenshaw responded to a Twitter user who also opposed the Ukraine assistance.

“[I]nvesting in the destruction of our adversary’s military, without losing a single American troop, strikes me as a good idea. You should feel the same,” Crenshaw told the critic.

Greene chimed in, accusing Crenshaw of wanting Ukrainian lives to be “thrown away.”

“So you think we are funding a proxy war with Russia?” Greene tweeted. “You speak as if Ukrainian lives should be thrown away, as if they have no value. Just used and thrown away. For your proxy war? How does that help Americans? How does any of this help?”

Crenshaw snapped back, accusing Greene of supporting Russia.

“Still going after that slot on Russia Today huh?” he tweeted.
