Whistle-blower complaint: Joe Biden demands probe, accuses Donald Trump of trying to ‘smear’ him

Joe Biden lashed out at Donald Trump, saying he could “beat him like a drum” and demanding a probe into allegations that the US president tried to bully Ukraine into joining a “smear” aimed at him.

“Trump’s doing this because he knows I’ll beat him like a drum,” Biden told reporters on the campaign trail in Iowa.

“He’s using the abuse of power and every element of the presidency to try to do something to smear me.”

The Democratic front-runner also wagged his finger at a reporter who asked whether he intervened with Ukraine on behalf of his son, Hunter, while serving as vice-president.

Biden lectured the reporter to focus on Trump’s reported abuse of power, which was the subject of a controversial whistleblower complaint that the White House is trying to squelch.

“You should be looking at Trump,” Biden scolded.
