On Tuesday, US senators will hear arguments from Ukraine’s President Volodymyr Zelenskyy and senior advisors to US President Joe Biden over the necessity of a new round of military support to help Ukraine stave off Russian invasion.

US officials have issued a grave warning, stating that by the end of the year, the US will have spent all of its resources for Ukraine. This comes at a time when Kyiv is struggling to make significant progress in its 2023 counteroffensive against Russia.

In October, the Biden administration requested approximately $106 billion from Congress to fund its ambitious plans for border security, Israel, and Ukraine. However, the package was rejected by Republicans in the House, who have a tiny majority.

In addition, a variety of top Biden officials, including Defense Secretary Lloyd Austin and Secretary of State Antony Blinken, are expected to brief the senators on Tuesday.

Schumer also started the process of advancing a Ukraine-Israel emergency aid bill on the Senate floor.

“America’s national security is on the line around the world” with the fate of Ukraine aid hanging in the balance, Schumer said in a Senate speech. “Autocrats, dictators waging war against democracy, against our values, against our way of life. That’s why passing this supplemental is so important. It could determine the trajectory of democracy for years to come.”
