The move may be a sign that congressional investigators are anticipating a fight in their efforts to compel certain witnesses to cooperate with their probe and want to accelerate the process by which the committee can subpoena testimony or documents from people involved.
They have already encountered resistance from Michael Flynn, the former national security adviser, who notified the committee through his attorneys this week that he would not comply with a subpoena request for documents detailing contacts he had with Russian officials between June 16, 2015, and Jan. 20, 2017, invoking his Fifth Amendment right against self-incrimination. The committee responded by narrowing the focus of their subpoena for records from Flynn and issuing two new subpoenas for records from Flynn's Virginia-based businesses.
The committee has not announced plans for additional subpoenas, though it is seeking documents and testimony from other members of the Trump campaign and transition teams. The committee is also planning to interview former FBI director James B. Comey in a public forum soon after Congress reconvenes, following a one-week recess next week. The committee has not announced a date for that hearing.
