House Intelligence Committee Chairman Devin Nunes (R-Calif.) said Thursday that he has reached a deal with Deputy Attorney General Rod Rosenstein for documents and interviews relating to FBI agents who were removed from special counsel Robert Mueller's team over anti-Trump text messages.

In a letter detailing an earlier conversation between the two men released by Nunes on Thursday night, the California Republican announced that the House Intelligence Committee will gain access to documents and text messages relating to agent Peter Strzok and his FBI colleague Lisa Page, as well as access to a number of FBI witnesses themselves, later in January.

The deal also grants the committee access to around 9,500 text messages sent between Strzok and Page, some of which were leaked to the press last year and revealed a perceived anti-Trump bias among the agents.

According to Nunes's letter, Republicans on the committee are interested in gaining the information as part of their investigation into the "Steele dossier," a memo of unverified claims about Trump's ties to Russia that Republicans believe was the impetus for the FBI's probe into the Trump campaign.

"The materials we are requesting are vital to the Committee's investigation of potential abuses into intelligence and law enforcement agencies' handling of the Christopher Steele dossier," Nunes wrote.

"The Committee is extremely concerned by indications that top U.S. Government officials who were investigating a presidential campaign relied on unverified information that was funded by the opposing political campaign and was based on Russian sources," he added.

The note adds that one document will be made available to the committee for private viewing due to national security concerns.

Nunes and the FBI have been at a stalemate for months over the documents, and last week the California lawmaker blasted Justice Department leadership for failing to turn over the documents.

"Unfortunately, DOJ/FBI's intransigence with respect to the August 24 subpoenas is part of a broader pattern of behavior that can no longer be tolerated," Nunes wrote last week. "At this point it seems the DOJ and FBI need to be investigating themselves."

Nunes was forced to recuse himself from the House Intelligence Committee's Russia probe last year after the House Ethics Committee began looking into his handling of classified information related to the investigation, which was taken over by Rep. Mike Conaway (R-Texas).
