• Trump on Thursday claimed not to know about a letter in which Rudy Giuliani claimed to be acting with the president's "knowledge and consent" in Ukraine. 
• "I don't know anything about the letter, but certainly Rudy is one of the great crime fighters in the history of our country," Trump told reporters in the Oval Office. 
• The letter was released by impeachment investigators on Tuesday, and was used by Giuliani as he sought an interview with Ukraine's president. 
• In the letter, Giuliani claimed to be acting with Trump's full "knowledge and consent" in Ukraine.
• It is one of the most significant pieces of evidence to emerge in the impeachment probe, apparently directly linking Trump to Giuliani's quest for Biden dirt.
