House Intelligence Committee ranking Democrat Rep. Adam Schiff is calling on Republican chairman Devin Nunes to release the transcript from the committee’s interview with Fusion GPS co-founder Glenn Simpson.

Schiff’s office said in a statement to Business Insider said he supported doing so because the role of Fusion GPS, an opposition research firm, has been mischaracterized after selective leaks of Simpson’s testimony.

“The Majority has released transcripts of Dr. Page and Mr. Prince when it suited their interests, and likewise should make an exception here,” Schiff said in his statement, referring to Carter Page, a Donald Trump campaign aide, and Erik Prince, an adviser to Trump’s transition team.

Fusion GPS hired former British spy Christopher Steele to research Trump and his potential ties to Russia during the 2016 presidential campaign.

A spokeswoman for the firm told Business Insider it supports releasing the transcript and has sent a letter to the committee to that effect, but that it has not been publicly released.
