Ukraine’s president said no one explained to him why U.S. military aid to his country was delayed.

President Volodymyr Zelensky told reporters Tuesday that he stressed the importance of the military aid repeatedly in discussions with President Donald Trump, but “it wasn’t explained to me” why the money didn’t come through until September.

The Office of Management and Budget staff said the $250 million in funding had been delayed because Trump was consulting with his national security team about it.

While delaying the aid, Trump asked the Ukrainian leader in a July phone call to “look into” his likely 2020 Democratic rival Joe Biden.

Zelensky insisted Tuesday that “it is impossible to put pressure on me.” He also said he has never met or spoken with Trump’s lawyer Rudy Giuliani, who has pushed for an investigation into Biden’s son Hunter, who was on the board of a Ukrainian gas company.
