A federal judge ruled Thursday that the Washington-based firm Fusion GPS cannot block the House Intelligence Committee from subpoenaing the firm's financial records, according to court documents.

Court records obtained by BuzzFeed News show that U.S. District Court Judge Richard Leon denied Fusion GPS's request for an injunction on the grounds that such a disclosure to Congress would violate the firm's First Amendment rights.

"Because I find all of Fusion's objections to the subpoena to be unavailing" the motion was denied, wrote Leon, an appointee of former President George W. Bush.

The House Intelligence Committee has been battling with Fusion GPS's founders for months over testifying before Congress and turning over documents related to the funding of research during the 2016 campaign into then-candidate Donald Trump Donald John TrumpHR McMaster says president's policy to withdraw troops from Afghanistan is 'unwise' Cast of 'Parks and Rec' reunite for virtual town hall to address Wisconsin voters Biden says Trump should step down over coronavirus response MORE's background.

Fusion GPS has bucked subpoenas from the committee before. In October, executives at the firm announced they would not comply with the panel's subpoena to testify, citing constitutional privilege.

"Should you compel any of our three clients to appear at the scheduled deposition, they will invoke their constitutional privileges not to testify," Fusion GPS counsel Josh Levy said. "Since that will be the case, we ask that the Committee excuse them from appearing."

The same month, the committee announced it had reached a settlement with Fusion GPS to obtain some initial bank records.

"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 said at the time.
