The United States’ ambassador to Poland, Tom Rose, said he was cutting all contact with Wlodzimierz Czarzasty, the speaker of the country’s lower house of parliament, known as the Sejm.

Rose accused Czarzasty of making “outrageous and unprovoked insults directed against [US President Donald Trump].”

Warsaw is one of the US’ closest allies in Europe and has one of the highest military budgets as a percentage of GDP within the US-led NATO military alliance.

Poland, which borders both Russia and Ukraine, is also one of Kyiv’s strongest supporters within the EU and its government has been skeptical of Trump’s efforts to negotiate a peace deal with Moscow.

What did Sejm speaker Czarzasty say about Trump?

The US envoy’s announcement comes after Czarzasty, who is a member of the center-left New Left party, said he would not support a bid to nominate Trump for the Nobel Peace Prize on Monday.

“I won’t support the application for a Nobel prize for Trump because he does not deserve it,” Czarzasty said.

“[Trump] represents power politics and, by the use of force, pursues transactional politics,” he argued.

The speaker criticized the US-led establishment of a new Board of Peace body tasked with overseeing the ceasefire in the Gaza Strip, calling instead for countries to strengthen pre-existing organizations such as the European Union, the NATO military alliance, the United Nations and the World Health Organization (WHO).

Czarzasty also took aim at Trump’s stated desire for the United States to take over the autonomous Danish territory of Greenland as well as comments downplaying the European contribution to the 2001-2021 US-led invasion of Afghanistan.

On Thursday, Czarzasty said that the US ambassador’s decision would not make him change his position.

“I regret the ambassador’s declaration, but I will not change my position on these fundamental issues for [Poland],” the speaker was cited as saying by Polish media.

KO-led government defends Czarzasty

Czarzasty’s New Left is part of Poland’s broad governing coalition under Prime Minister Donald Tusk of the center-right Civic Coalition (KO) party.

Tusk criticized Rose’s comments in a post on the platform X.

“Allies should respect, not lecture, each other. At least this is how we, here in Poland, understand partnership,” Tusk said in a post addressed to the US envoy.

The row sparked criticism from US politicians, with Republican lawmaker Don Bacon declaring: “Time for a new Ambassador.”

Meanwhile, KO lawmaker Zbigniew Konwinski accused Rose of threatening the Polish government.

“Ambassador Rose smoothly switched from an attack on the speaker of the Sejm to threats against the government,” he said on X, adding that he found this to be an “astonishing” form of diplomacy.

Warsaw caught between Brussels and Washington

Poland is a European Union member state and the disparate parties in its current coalition government have typically called for closer ties with Brussels.

Meanwhile, Polish President Karol Nawrocki — whose June 2025 election bid was endorsed by Trump — is closely aligned with the opposition nationalist Law and Justice (PiS) party that has called for a looser EU.

Poland’s president can veto legislation and serves as the commander-in-chief of the army, while other executive powers are in the hands of the prime minister and the Cabinet.

Trump told Nawrocki during an Oval Office meeting in September that the US did not intend to withdraw troops from Poland, saying: “We’ll put more there if you want.”
