“He wants me to do it,” Giuliani said in a brief interview. “I’m working on pulling it together and hope to have it done by the end of the week.”

However, it is unclear whether GOP senators or Justice Department officials want information from Giuliani, whose meetings in Europe last week with Ukrainian sources drew condemnation from Democratic lawmakers and winces even from some Republicans.

In a recent interview, Sen. Lindsey O. Graham (R-S.C.) said he had no plans for Giuliani to appear before the Senate Judiciary Committee, which has launched an inquiry into former vice president Joe Biden and his communications with Ukrainian officials. Attorney General William P. Barr has counseled Trump in general terms that Giuliani has become a liability and a problem for the administration, as The Washington Post previously reported.
