Over the course of the afternoon, Bondi, the former Florida attorney general, and Herschmann featured clips of the elder Biden talking about his work in Ukraine, as well as footage of his son's recent televised interview about Burisma.

Democrats impeached Trump last month on charges that he pressured Ukraine to investigate Biden and other Democrats in order to benefit his 2020 reelection. Trump defenders say his interest in pursuing a Biden probe was a genuine reflection of his concerns about corruption and that they viewed Biden suspiciously for seeking the removal of a Ukrainian prosecutor who was supposed to be investigating Burisma.

But witnesses told the House throughout the fall that the impression created by Trump's allies was false -- that in fact, Biden's attempt to remove Ukraine's top prosecutor was in support of U.S. foreign policy any backed by the international community. Far from investigating Burisma, they said, the prosecutor was sidestepping an investigation of the company and his removal made it likelier that Burisma would face a legitimate probe.

The Biden campaign and Senate Democrats pushed back vehemently against the Trump defense team’s arguments, and have long argued that the attacks against the former vice president have no basis in fact.

Andrew Bates, a spokesperson for Biden, said shortly after Bondi’s presentation that she was doing nothing more but spreading conspiracy theories that have been debunked by major news organizations, including the New York Times, the Wall Street Journal and the Washington Post.

"We didn't realize that Breitbart was expanding into Ted Talk knockoffs. Here on planet Earth, the conspiracy theory that Bondi repeated has been conclusively refuted,” Bates said in a statement. “Joe Biden was instrumental to a bipartisan and international anti-corruption victory. It's no surprise that such a thing is anathema to President Trump."

During the Senate trial, Bondi argued that she was merely responding to the arguments from House impeachment managers, who she said mentioned the Biden family and Buisma during their opening arguments more than 400 times. But Senate Democrats saw nothing more than a political attempt to damage the former vice president.

“The first part just seemed to be a big 2020 campaign commercial list of the president's campaign highlights and bashing the Bidens,” said Sen. Chris Murphy (D-Conn.). “From the very beginning it seems as if the president was so focused on Joe Biden partly because he knew Joe Biden was a strong candidate.”

“Look at the hour, look when they did it,” added Sen. Jon Tester (D-Mont.) “It had nothing to do with what the president did.”
