Watch full speech: Bill Clinton swipes at Trump’s age in DNC speech

Viktor Orbán, the autocratic Hungarian president and staunch Russian ally, conceded defeat in the country's national election on Sunday, ending his 16-year reign in power, according to reports.

The Associated Press reported that with 60% of the vote counted, opposition leader Peter Magyar’s party held 52% of the vote compared to Orbán's 38% support. Orbán described the loss as "painful."

"It’s a major blow for Orbán, the European Union’s longest-serving leader and one of its biggest antagonists, who has traveled a long road from his early days as a liberal, anti-Soviet firebrand to the Russia-friendly nationalist admired today by the global far-right," the AP reported.

Trump endorsed Orbán in a Truth Social post on Friday, calling him " a truly strong and powerful leader." Trump added that the U.S. stood ready to "strengthen Hungary's economy," if Orbán won.
