CNN is standing by its story that Michael Cohen, President Trump's former personal attorney, claimed he was willing to tell special counsel Robert Mueller that Trump knew about the 2016 Trump Tower meeting between campaign officials and the Russians.

Why it matters: Lanny Davis, Cohen's attorney, admitted he was one of CNN's anonymous sources for the story, but backed off his original claim instead saying Cohen does not know if Trump knew about the meeting. A CNN spokeswoman said the story, which CNN first reported in July, had "more than one source" and the organization remained confident in its reporting despite Davis' flip.
