“There’s very often a slippery slope when these military aid transfers happen,” Rep. Alexandria Ocasio-Cortez (D-NY), who has previously voiced support for the military aid being sent to Ukraine, said. “There’s a way that it can be very targeted and there’s a way that it can be very indiscriminate… Who specifically is on the receiving end is very important and what specifically is being sent is also very important.”

Rep. Ilhan Omar (D-MN), who came to the United States as a refugee from war-torn Somalia as a child, tweeted that she’s concerned about the prospect of “flooding Ukraine” with billions of dollars in American weapons, calling the consequences “unpredictable” and “likely disastrous.”

Omar added the role of paramilitary groups in Ukraine—essentially unofficial defense forces—gives her pause. “​​I support giving Ukraine the resources it needs to defend its people, I just have legitimate concerns about the size and scope,” she wrote.
