A whistleblower complaint filed August 12 reportedly alleges that President Donald Trump tried to pressure the Ukrainian government to investigate Democratic presidential candidate Joe Biden. Now, Trump and his allies are trying to muddy the waters and turn a conspiracy theory involving Joe Biden and Ukraine into an allegation of corruption against Biden.

The Biden-Ukraine connection began as an internet conspiracy theory that burst into the mainstream last week. On September 18, The Washington Post reported that a whistleblower complaint filed August 12 involved Trump’s communications with a foreign leader. Trump’s interaction included a “promise” that was “regarded as so troubling that it prompted an official in the U.S. intelligence community to file a formal whistleblower complaint with the inspector general for the intelligence community.” Speculation and additional reporting suggested that the complaint involved Trump requesting that Ukraine open an investigation into former Vice President Joe Biden’s role in potentially halting an investigation into a Ukrainian energy company whose board members included his son, Hunter Biden. On September 19, Trump personal lawyer Rudy Giuliani appeared on CNN’s Cuomo Prime Time and denied, then admitted, then denied again that he had asked Ukraine to investigate the Bidens. Additional reporting from The Wall Street Journal and The New York Times appeared to confirm the whistleblower complaint, providing new additional details. The Post and the Times then both confirmed that Giuliani had met with an aide days after Trump’s call to spell out more specifics

Trump and his allies are relying on the complexity of the story to muddy the waters, pushing out a slew of myths in a rush to provide cover for Trump as details surrounding the story continue to emerge. Trump’s allies in right-wing media are frantically trying to reframe the story to be about Biden’s supposed corruption in Ukraine, push false or misleading information about the Ukrainian prosecutor at the center of the story, discredit the whistleblower as a “deep state” snitch seeking to undermine Trump, insist that Trump was just engaging in run-of-the-mill foreign policy discussions, and assert that the Trump administration doesn’t have a responsibility to turn the complaint over the Congress.

Here are six myths and facts surrounding Trump, Biden, Ukraine, and the whistleblower complaint:
