WASHINGTON (AP) — Key Republicans and Democrats in Congress have been stalwart supporters of Ukrainian President Volodymyr Zelenskyy, but the blowup between the Ukrainian leader and President Donald Trump is threatening to change that.

House Speaker Mike Johnson (R-La.) tells Meet the Press that the United States remains committed to its allies despite President Trump’s heated Oval Office exchange with Ukrainian President Volodymyr Zelenskyy but says America’s allies “have to be reasonable.

"Once you’ve lost Lindsey Graham, that means you need to come to the negotiating table," the vice president said.

Top Republicans aligned with U.S. President Donald Trump pushed Ukrainian President Volodymyr Zelenskiy on Sunday to change his position on the war with Russia or step aside, ramping up pressure on the Ukrainian leader after a contentious White House meeting last week.
