The months-long dance between President Trump’s lawyers and Robert Mueller over a voluntary presidential interview has yet to bear fruit, raising the question of whether the special counsel will subpoena the president to testify as part of his Russia probe.
Those who know Mueller professionally say he would not hesitate to compel Trump to testify under oath before a grand jury if he considered it critical that his investigation include testimony from the commander in chief.
Stephen Vladeck, a University of Texas law professor who has been closely watching the investigation, said that Mueller would subpoena Trump only if he “believes he has exhausted all other options and if he really thinks it is necessary.”
“Before you subpoena the president you want to make sure you have every single duck in a row,” Vladeck said.
