Mr. Sasse added that the United States “should absolutely send Ukrainians planes, helicopters and U.A.V.s,” or unmanned aerial vehicles.
In an interview after the call, Representative Tom Malinowski, Democrat of New Jersey, suggested that Congress quickly approve funding to reimburse Eastern European allies if they provide Ukraine with planes — or more feasibly, he said, surface-to-air missiles.
“We should be signaling to the Poles and Romanians and others that this is something we would want to help them do,” Mr. Malinowski said.
Senator Chuck Schumer, Democrat of New York and the majority leader, pledged to Mr. Zelensky during the call that he and Senator Mitch McConnell, Republican of Kentucky and the minority leader, were working “very hard in a bipartisan fashion” to quickly approve the $10 billion aid package to Ukraine that the Biden administration requested this past week.
“President Zelensky made a desperate plea for Eastern European countries to provide Russian-made planes to Ukraine,” Mr. Schumer said in a statement. “These planes are very much needed. And I will do all I can to help the administration to facilitate their transfer.”
On the call, Mr. Zelensky also asked for Western governments to impose additional sanctions on Russia. And in a tart aside, he said he believed that Russia would not have invaded Ukraine if the penalties recently imposed by the Biden administration and European governments had been enacted in the fall, according to two people familiar with the comments.
