President Donald Trump on Wednesday repeatedly evaded questions from reporters about comments he made during a July phone call with Ukrainian President Volodymyr Zelensky regarding Joe Biden.

During a press conference at the White House with Finland’s President Sauli Niinistö, Reuters correspondent Jeff Mason asked Trump to explain what exactly he had wanted Zelensky to do about the former vice president and his son, Hunter.

In his long-winded response, Trump defended his phone call with Zelensky and bashed Europe for not giving more money to Ukraine. He then told Mason to ask Niinistö a question, but another reporter interrupted to press Trump about Biden.

“Look, Biden and his son are stone cold crooked,” Trump claimed. “You know it and so do we.”

Trump has accused then-Vice President Biden of calling for the removal of a corrupt prosecutor in Ukraine for the purpose of impeding an investigation into the Ukrainian gas company upon whose board Hunter Biden was serving. Ukrainian authorities have cleared Biden of any wrongdoing.

Mason pushed Trump again: “But the question, sir, was what did you want President Zelensky to do about Vice President Biden and his son Hunter?”

“Are you talking to me?” Trump asked after a few moments of silence. “Haven’t you finished with me? Listen, we have the president of Finland. Ask him a question.”

But Mason continued to press Trump to answer the question, drawing heated pushback from the president.

“Ask him a question,” Trump said, motioning to Niinistö. “Don’t be rude. ... I’ve answered everything. It’s a whole hoax. And you know who’s playing into the hoax? People like you and the fake news media.”
