Zelensky said on his Instagram account that the visit “is a strong signal of bipartisan support for Ukraine from the US Congress and the American people”.
He added: “Thank you for your leadership in helping us in our struggle not only for our country, but also for democratic values and freedoms. We appreciate it very much.”
Republican Senator Susan Collins of Maine, John Barrasso of Wyoming and John Cornyn of Texas also met Zelensky in videos and photos posted to the Ukrainian president’s social media accounts.
It is unclear whether the meeting took place on Saturday and whether the delegation is still in the Ukrainian capital.
McConnell and the other senators are the last US officials to visit Ukraine since Russia invaded the Eastern European country in late February. Two weeks ago, House Speaker Nancy Pelosi led the first congressional delegation to Ukraine since the outbreak of war. Pelosi, accompanied by several senior House Democrats, met with Zelensky in Kiev.
First lady Jill Biden met Ukrainian First Lady Olena Zelenska last weekend in Uzhhorod on the Slovakian border at a converted school that now serves as temporary housing for displaced citizens. US Secretary of State Antony Blinken and Defense Secretary Lloyd Austin met with Zelensky in Kiev last month.
Congress has been trying to pass a roughly $40 billion relief bill that would provide Ukraine with military and humanitarian aid. In a rare show of unity, McConnell and Senate Majority Leader Chuck Schumer pushed for a swift approval of the bill this week after the House proposed the measure in a bipartisan vote. However, that Senate effort was blocked by GOP Sen on Thursday. Rand Paul of Kentucky, who has demanded changes to the law. The Senate is expected to pass the bill sometime next week, forcing Schumer to take procedural steps to address Paul’s objection before it is sent to President Joe Biden’s office.
