Senate Republicans on Wednesday said congressional efforts to press the Biden administration on its response to Russian President Vladimir Putin’s invasion of Ukraine have been largely bipartisan while calling on President Joe Biden to take additional steps.

Shortly after Ukrainian President Volodymyr Zelensky delivered a virtual address to Congress, Biden said the United States will provide Ukraine with an additional $800 million in military aid, including anti-aircraft defenses Zelensky referenced in his address. The additional aid was some, but not all, of what Zelensky requested. The Ukrainian president has called for a NATO-led no-fly zone over Ukraine to reduce attacks from Putin’s forces, but many lawmakers appear to prefer equipping Ukraine to enforce its own no-fly zone, keeping U.S. forces out of direct conflict.
