President Donald Trump has called on Democratic presidential candidate Joe Biden to release the documents linking to his family’s business dealings after a New York Post story exposed the Bidens dealing with Ukrainian natural gas company Burisma Holdings.

Speaking at a campaign rally in Des Moines, Iowa on Wednesday, Oct. 14, the president said, “Joe Biden must immediately release all emails, meetings, phone calls, transcripts, and records related to his involvement in his family’s business dealings, influence peddlings around the world, including China and including Russia.”

His response came after the New York Post unveiled—in a bombshell article published on Wednesday morning—that Joe Biden’s son Hunter introduced him to a top executive at Burisma, among other potentially criminal acts.

About a year later, the then U.S. vice president pressured Ukraine to fire a prosecutor investigating the corrupt energy company Burisma where his son Hunter was on the management board.

The former vice president, who was in charge of the Ukraine portfolio during President Barack Obama’s second term, has repeatedly claimed he kept his distance from his son’s business abroad.

The article said that a water-damaged MacBook Pro that belonged to Hunter Biden was turned over to the FBI by a computer repair shop owner. The FBI seized the laptop’s hard drive, but a copy handed to President Donald Trump’s attorney Rudy Giuliani ended up in the hands of the New York Post.

The Post released some emails and photos related to Hunter in its article, which Twitter and Facebook blocked from sharing on their networks.

Twitter has locked the personal account of White House Press Secretary Kayleigh McEnany for sharing the article.

Even President Trump’s official campaign account, @TeamTrump, was also blocked by Twitter on Oct. 15, just three weeks before the election. President Trump criticized Twitter and Facebook for limiting links to the New York Post story during his campaign event.

“These emails show that Biden’s repeated claim that he has never spoken to Hunter about his business dealings were a complete lie,” the president said. “It was a total lie. He lied to you over and over because he’s trying to cover up a massive pay-to-play scandal at the heart of his vice presidency.”

“The Bidens got rich, and America got robbed,” President Trump said. “I cannot sit idly by and watch career politicians like Joe Biden continue bleeding this country dry.”

President Trump said, “Hunter raked in a fortune from China while Joe Biden was giving China all of our jobs.” He added that “I ran for president because I could not sit back any longer and watch the terrible injustices being done to the American people.”
