The committee, one of several investigating Russian efforts to influence the election and allegations of collusion, subpoenaed Fusion GPS and the firm's bank on Oct. 4.
"The emergency legal action taken last week by Fusion GPS helped the company honor its legal obligations and protect its First Amendment rights," Fusion GPS lawyer Joshua Levy said in a statement. "Today's result required the involvement of the Court to strike the balance between Congress' right to information and our client's privileges and legal obligations."
The committee issued a statement confirming a deal.
"The parties have reached an agreement related to the House Intelligence Committee's subpoena for Fusion GPS's bank records that will secure the Committee's access to the records necessary for its investigation," the committee statement said.

"By its terms, the engagement concluded prior to the November 2016 Presidential election."
