"In an abundance of caution-to ensure that Mr. Whitaker both appears in the hearing room on Friday morning and answers our questions cleanly ̵
"For the first two years of the Trump Administration, government witnesses allowed dodge uncomfortable questions. That era is over," he continued.
If the subpoena is "unnecessary" if Whitaker appears Friday morning as scheduled.
"No need to be here. We have been quite public about our intention to obtain this information from Mr. Whitaker," the New York lawmaker concluded.
The strategic move also calls further public at the high-profile hearing in which Whitaker will appear before the House Judiciary Committee on Friday morning.
Lawmakers reached a deal with Whitaker last month, in which he agreed to testify regardless of whether the partial government shutdown was still ongoing and regardless of whether he was still the Justice Department's interim top cop. 
The Judiciary Chairman has also taken other measures to prevent Whitaker from avoiding particular issues when he appears before the committee by also sending him a series of questions in advance.
