Donald Trump publicly urged voters in Hungary to support Prime Minister Viktor Orbán in the country’s upcoming election.

Donald Trump praised Viktor Orbán as a strong leader and formally endorsed him, highlighting close United States-Hungary relations.

The endorsement comes as Viktor Orbán faces a difficult reelection challenge from the opposition Tisza party ahead of the April 12 vote.

Viktor Orbán, in power since 2010, has been a polarizing figure due to his governance style and ties to Russia, The Hill has reported.

The election is widely seen as a referendum on Hungary’s political direction and its role in the European Union and NATO.
