Marco Rubio will visit Hungary and Slovakia in the coming days, as the U.S. secretary of state tours key American allies in Central Europe after attending the Munich Security Conference.

The top diplomat will “meet with key Hungarian officials to bolster our shared bilateral and regional interests,” a State Department spokesperson said. Rubio’s visit takes on added significance ahead of an April election, where Prime Minister Viktor Orbán faces a tough challenge from conservative Tisza party leader Péter Magyar.

President Donald Trump threw his support behind Orbán last week, saying he has “my Complete and Total Endorsement for Re-Election as Prime Minister of Hungary.”

The Hungarian leader’s nationalist Fidesz party has become a model for MAGA-linked populists, especially for its hard-line approach to minority rights and migration — but Magyar’s Tisza party is currently running 11 points ahead, according to POLITICO’s Poll of Polls.

The U.S. administration has hinted — in the U.S. National Security Strategy published last November — that it could assist ideologically allied European parties, which would include Orbán’s Fidesz or Slovak Prime Minister Robert Fico’s Smer, to keep the continent from what it describes as “civilizational erasure.”

In Slovakia, Rubio plans to discuss regional security interests, commitments to NATO and strengthening bilateral cooperation on nuclear energy.
