The president's contacts with Ukraine have come under intense scrutiny after an intelligence whistleblower filed a complaint related to his communications with the nation.
Biden, exiting a campaign event shortly after the story broke, declined to address the report directly but called the allegations of any wrongdoing in Ukraine baseless.
“Not one single credible outlet has given any credibility to his assertions — not one single one.
And so I have no comment, except the president should start to be president," Biden told reporters.
Trump was asked earlier Friday whether he had discussed Biden or his son with the Ukrainian president.
The president has further dismissed the whistleblower complaint as a “political hack job” and decried the whistleblower as “partisan.”.
But Trump acknowledged that he has not read the complaint and that he does not know the individual’s identity. »
