President Trump claimed Friday it "doesn't matter" what he discussed with Ukraine amid the ongoing scandal over a whistleblower's "urgent" concern.

Trump spoke in the Oval Office following days of reporting about a whistleblower's complaint filed in August reportedly about a troubling "promise" Trump made on a call with a foreign leader. The Washington Post reported Thursday it has to do with Ukraine, and weeks before the complaint, Trump spoke over the phone with Ukrainian President Volodymyr Zelensky.

But questioned Thursday about conversations with Ukraine, and about whether he spoke about former Vice President Joe Biden and his son, Trump deflected.

"It doesn't matter what I discussed," Trump said. "But I will say this: somebody ought to look into Joe Biden's statement, because it was disgraceful."

Trump's attorney, Rudy Giuliani, admitted in a CNN interview Thursday he asked Ukraine to investigate Biden over an allegation he bribed the country's former president to fire a prosecutor investigating his son. The president Friday seemed to be referring to Biden's statement recalling telling Ukraine "you're not getting" a billion-dollar loan guarantee if the prosecutor wasn't fired, although PolitiFact writes this was also "the position of the wider U.S. government, as well as other international institutions" and "we found no evidence to support the idea that Joe Biden advocated with his son's interests in mind."

The president Friday attacked the whistleblower as "partisan" even though he admitted he has no idea who it is. "I just hear it's a partisan person," he said. He also claimed his conversation was "beautiful" despite subsequently admitting "I really don't know" what conversation the complaint concerns. Brendan Morrow
