According to Politico, even before the request has reached the House of Representatives, divisions in the Senate threaten to sink the proposal or radically change it. As the WSJ wrote, both parties in Congress supported aid to Israel after the October 7 attack by Hamas. However, some Republicans are skeptical of new funding for Ukraine, while others prefer to fund weapons over humanitarian or direct economic aid to the Ukrainian government.
Some Republicans want aid to Israel to be separated from aid to Ukraine because “the latter has become politically unpopular with their party’s constituents and several Republican lawmakers.”
The WSJ notes that Congress has already approved over $100B for Ukraine since Russia invaded on February 24, 2022.
In addition, Mike Johnson has been elected as the 56th speaker of the House, and has also been opposed to Ukrainian aid. Johnson is known as a conservative Republican and an ally of Donald Trump, leading to more uncertainty for US aid to Ukraine.
