A government source told Fox News that the intelligence community wanted to give Trump a heads-up that the allegations had been widely circulating and that a lot of media outlets were sitting on the story. The source said the claims did not constitute a "central element" of Trump's briefing. 

CNN initially reported that Trump and President Barack Obama were presented with a two-page summary that detailed the allegations. The report said the summary was attached to a broader report about Russian operatives' activities during the 2016 election.

At a contentious press conference earlier Wednesday, Trump said that he had learned details of the allegations "outside of the meeting" with intelligence officials.  http://www.foxnews.com/politics/2017/01/11/trump-was-not-given-any-summary-russian-claims-about-compromising-info-source-says.html
