Joe Biden is continuing to hammer President Trump over a leaked whistle blower complaint about a call Trump allegedly had with a foreign leader.

Fox News reporter Peter Doocy asked Biden on Saturday if he ever talked to his son, Hunter Biden, about overseas business, and Biden snapped over the question.

“Here’s what I know,” Biden said pointing his finger in Doocy’s face, “I know Trump deserves to be investigated.

“He’s violating every basic norm of a president,” Biden said in Des Moines, Iowa.

“You should be asking him the question, why is he on the phone with the foreign leader, trying to intimidate a foreign leader, if that’s what happened, that appears what’s happened,” he continued, still wagging his finger in Doocy’s face.

“You should be looking at Trump. Trump’s doing this because he knows I’ll beat him like a drum, and he’s using the abuse of power and every element of the presidency to try to do something to smear me,” Biden claimed.

“Ask the right questions,” Biden angrily barked in Doocy face before turning away from the reporter.

The AP reports on the call:

President Donald Trump urged the new leader of Ukraine this summer to investigate the son of former Vice President Joe Biden, a person familiar with the matter said Friday. Democrats condemned what they saw as a clear effort to damage a political rival, now at the heart of an explosive whistleblower complaint against Trump.

It was the latest revelation in an escalating controversy that has created a showdown between congressional Democrats and the Trump administration, which has refused to turn over the formal complaint by a national security official or even describe its contents.

Trump defended himself Friday against the intelligence official’s complaint, angrily declaring it came from a “partisan whistleblower,” though he also said he didn’t know who had made it. The complaint was based on a series of events, one of which was a July 25 call between Trump and Ukrainian President Volodymyr Zelenskiy, according to a two people familiar with the matter. The people were not authorized to discuss the issue by name and were granted anonymity.

“I have conversations with many leaders. It’s always appropriate. Always appropriate,” Trump told reporters in the Oval Office. “At the highest level always appropriate. And anything I do, I fight for this country.”
