Vance visits Hungary to back Orbán

Vance is scheduled to meet with Orbán and deliver a speech highlighting the strategic importance of the U.S.-Hungary relationship.

The Hungarian leader faces his toughest electoral challenge in years, with opposition polls showing young voters trending toward a change in government.

The visit also comes amid controversy over Hungary's ties to Russia and its opposition to European Union policies.

For the White House, Orbán remains a cornerstone of their vision for a conservative, nationalist-led Europe.
