Donald Trump intends to visit Hungary's Orbán during key election campaign

US President Donald Trump teased a visit to Hungary at the invitation of Hungarian Prime Minister Viktor Orbán as the country readies for a crucial election in April.

According to a letter published by Orbán, Trump praised what he called the "golden era of American-Hungarian relations" and highlighted his interest in deepening cooperation in the areas of defense, energy, and our shared fight against illegal migration.

"Your leadership serves as an example to others around the world. You have consistently stood for the principles that make Hungary strong — faith, family, and national sovereignty — and America respects that courage" Trump wrote.

Trump hosted Orbán in Washington in last November for talks, where Hungary secured an exemption for one year from US secondary tariffs hitting Russian oil exports. Orbán invited Trump to Hungary at the time.

"I am honoured by your invitation to visit Hungary. My team will be in touch soon to coordinate scheduling," Trump wrote in his letter.

The visit looks set to coincide with Hungary's election campaign ahead of a high-stakes election in April.

According to opinion polls, Orbán's challenger, the Tisza party led by Péter Magyar, is ahead of the ruling coalition Fidesz-KDNP. In his message, Trump also referred to the election campaign.

"I wish you the best luck in the upcoming election campaign.”

The Trump administration said in a controversial national security document last year that it would foster relations with parties and governments resisting the “current trajectory” of the EU from within.

In November, Trump praised Orbán as a "great leader" and praised his efforts to curb illegal migration.
