Rubio met Orbán, says they have a very close relationship

"The prime minister and the president have a very, very close personal and working relationship," Rubio said at a press conference.

I think it has been beneficial for both our countries.

Rubio met on Sunday with another Trump-friendly leader, Slovak Prime Minister Robert Fico.

Trump himself has recently emphasized his support for the EU-critical Orbán ahead of the Hungarian parliamentary elections in April.

Orbán's Fidesz party is facing headwinds in public opinion. Challenger Péter Magyar drummed his message this weekend that "Hungary's place is in Europe" when his Tisza party kicked off the election campaign.
