U.S. President Donald Trump held a telephone conversation today (Tuesday) with Hungarian Prime Minister Viktor Orbán in an attempt to convince him to stop blocking Ukraine’s accession to the European Union, according to reports.

The call took place after extensive discussions at the White House involving Trump, Ukrainian President Volodymyr Zelensky, and several European leaders, who sought to coordinate a unified approach to ending the war with Russia.

During the meeting, the visiting leaders urged Trump to use his close ties with Orbán, his ally, to remove Hungary’s opposition to Ukraine’s membership bid.

According to reports, Hungary also expressed interest in hosting another round of talks between Russian President Vladimir Putin and Zelensky.

Following the discussions, Trump announced his intention to promote a leaders’ summit between Russia and Ukraine, to be followed by a trilateral meeting including himself.

However, the date and location of the meetings have not yet been determined.

White House officials declined to comment officially on the call, and Orbán himself did not confirm it took place.

The following day, however, he published a statement on Facebook implying that he did not intend to change his position: “Ukraine’s membership in the European Union does not provide sufficient security guarantees.

Linking membership to security guarantees is unnecessary and dangerous.”

The conversation between Trump and Orbán occurred just days after the U.S. President’s meeting with Putin in Alaska, described as “critical” for advancing new diplomatic initiatives aimed at ending the war, which has already lasted more than three years.
