“We would move to quash the subpoena,” Giuliani said in an interview. “And we’re pretty much finished with our memorandum opposing a subpoena.”…

In recent weeks, Giuliani said members of Trump’s team have “had conversations” with Emmet T. Flood, a White House lawyer working on issues related to the federal investigation. He said Flood “would have a big role to play here and would assert presidential privilege” but declined to say more about those discussions.

White House officials have privately said Flood has cautioned Trump and others about the unpredictability of a subpoena fight that could be decided by the Supreme Court. Such a case would be unprecedented. Independent counsel Kenneth W. Starr served President Bill Clinton with a subpoena to compel him to appear before a grand jury, but it was withdrawn after Clinton agreed to testify.
