Rudolph W. Giuliani, one of the president’s personal lawyers, acknowledged the arrangement on Tuesday and defended it as a source of valuable insights into the special counsel’s inquiry and where it was headed. Such information could help shape a legal defense strategy, and it also appeared to give Mr. Trump and his legal advisers ammunition in their public relations campaign against Mr. Mueller’s office.
For example, Mr. Giuliani said, Mr. Manafort’s lawyer Kevin M. Downing told him that prosecutors hammered away at whether the president knew about the June 2016 Trump Tower meeting where Russians promised to deliver damaging information on Hillary Clinton to his eldest son, Donald Trump Jr. The president has long denied knowing about the meeting in advance. “He wants Manafort to incriminate Trump,” Mr. Giuliani declared of Mr. Mueller.
