Republicans are demanding a private memo shown to the US intelligence committee is made public.
The hashtag #ReleaseTheMemo began trending on Twitter after a number of Republicans took to the social media site to call for its release.
While they could not reveal its contents, some of those who read the document have raised alarm.
Congressman Steve King branded the issue “worse than Watergate”.
Others described what they read as “alarming” and “shocking” as they rallied for the report to be released after it was shown to all members of the House.
I have read the memo. The sickening reality has set in. I no longer hold out hope there is an innocent explanation for the information the public has seen. I have long said it is worse than Watergate. It was #neverTrump & #alwaysHillary. #releasethememo— Steve King (@SteveKingIA) January 19, 2018
I viewed the classified report from House Intel relating to the FBI, FISA abuses, the infamous Russian dossier, and so-called "Russian collusion." What I saw is absolutely shocking.— Mark Meadows (@RepMarkMeadows) January 19, 2018
This report needs to be released--now. Americans deserve the truth. #ReleaseTheMemo pic.twitter.com/oP2UNujKQL
According to US media, reports suggest the memo may contain answers to allegations surrounding the FBI, the US Justice Department and the “Trump dossier”.
The dossier, which was published in full by BuzzFeed in January last year, contains a number of unverified claims about US President Donald Trump's ties to Russia.
