Schiff on Wednesday wrote Nunes a letter charging that "material changes" were made to the memo after the committee voted on it, and the version given to the White House "is not, in fact, the same document".
Democrats paint the memo, crafted by Republican members of the House Intelligence Committee, as misleading and meant to discredit the criminal probe into potential collusion between Trump's presidential campaign and Russian Federation. Rep. Adam Schiff of California, the ranking Democrat on the Intelligence Committee, has called the memo that Nunes wants to release little more than a "conspiracy theory".
Both Pelosi and Senate Democratic Leader Charles Schumer asked Speaker Ryan to take Nunes off the Intelligence Committee, a suggestion that was immediately rejected by Ryan, who said Democrats were just playing "political games".
Democrats say the memo could be used by Republicans to try to undermine the credibility of Special Counsel Robert Mueller's investigation into possible collusion between Trump's presidential campaign and Russian Federation to help him win the 2016 election.
The Republican memo is predicted to reflect badly on Justice Department Deputy Attorney General Rod Rosenstein, who is overseeing Mueller's probe of the Trump campaign, and allegations the president obstructed justice by attempting to stymie the FBI's original investigation. Wray, appointed by Trump, has urged the memo not be released. It has now come to our attention that Congressman Nunes deliberately and materially altered the contents of the memo since it was voted on by the House Republicans.
Officials familiar with the Page case have said Steele's information represented a small part of the secret court document.

A spokesman for Nunes reportedly said the changes were minor.
There has been speculation that Mr Wray might resign if Mr Trump allows release of the memo.
It looks like the controversial four-page memo that may contain details of government surveillance abuses leading up to the 2016 presidential election is going to be made public soon - and it could make a big splash in Washington, DC.
Kelly delivered the memo to Trump on Wednesday, and the pair briefly discussed it before Trump read the document.
