For Ukraine and its supporters, the sudden death of U.S. Sen. Lindsey Graham raises an important question: Without a close ally of U.S. President Donald Trump advocating loudly for Ukrainian President Volodymyr Zelenskyy¡¯s government, will his administration¡¯s recent tilt in favor of Kyiv last?

The answer will especially affect two major issues ¡ª legislation to sanction Russia, which Graham pushed for more than a year, and military assistance for Ukraine.

On both, the momentum has lately been in Ukraine¡¯s favor as Kyiv faces intensified attacks by Russia and pressure to ?end the nearly 4?-year conflict.
