to ukraine. now, pomds was asked about this briefly when reporters caught him in new york on the sidelines of the u.n. general assembly. he said everyone to his knowledge at the state department had acted entirely appropriately. the keyword is to his knowledge. were there things happening not to his knowledge? we know that ambassador curt volcker in charge of relations with ukraine from the state department had been dealing with rudy guiliani. he had been talking with him. he had been texting with him. sources tell me that secretary of state mike pompeo had signed off on those talks. so the question is what is pompeo going to provide to the committees, what is he going to admit to knowing and when he knew it. >> i believe ambassador volcker was putting giuliani in touch with prosecutors in ukraine, prosecutors that giuliani hoped to convince to continue to investigator to investigate the president's political opponents,
