President Trump on Sunday accused Democratic rival Joe Biden of lying when he claimed that he hadn’t spoken to his son Hunter about his foreign business dealings while characterizing his talks with the Ukrainian president as “perfect.”

Trump said the phone call with President Volodymyr Zelensky covered a number of topics, including congratulating him on his election victory and discussing corruption in Ukraine.

It was “largely the fact that we don’t want our people like Vice President Biden and his son [contributing] to the corruption already in the Ukraine, and Ukraine has got a lot of problems.”

Describing his July 25 call to Zelensky “perfect,” Trump said what “wasn’t perfect is the horrible thing that Joe Biden said, and now he made a lie when said he never spoke to his son.”

Trump also faulted the whistleblower who last month reported the conversation to the inspector general of the intelligence community as putting out “false alarms,” adding “you can’t have that happen to a president of the United States.”

In an interview with the New Yorker in July, Hunter said he and his father had an agreement that he wouldn’t talk about who he was lobbying and his dad wouldn’t ask about his clients.

But he admitted that Biden talked to him about his position with Burisma Holdings “just once.”

Burisma was under investigation for corruption by Ukraine’s top prosecutor Viktor Shokin in 2016 when the then-vice president said the US would cancel $1 billion in aid unless Shokin was removed.

Biden, beating back Trump’s allegations during a campaign stop Saturday in Iowa, denied talking to his son Hunter about “overseas business dealings” and suggested that “Trump should be investigated.”

Ukrainian prosecutors have said they did not uncover any evidence the Bidens did anything wrong.

Trump, according to reports, repeatedly pressured Zelensky to cooperate with his lawyer Rudy Giuliani to investigate Hunter and even dangled $250 million in US military aid to Ukraine.

The president has denied those accusations and told reporters in Houston on Sunday that he’s considering releasing a transcript of the call.

The whistleblower’s report was handed over to the acting Director of National Intelligence Joseph Maguire who has refused to hand it over to Congress.

House Speaker Nancy Pelosi said Democrats expect Maguire “to obey the law” and turn over the complaint when he appears before the House Intelligence Committee on Thursday.
