Most of the major papers published false (and hence unverified) claims from the Steele dossier before the 2016 election. Buzzfeed then published it in full in January 2017.
I don't know what you are considering examples of claims from the dossier or what you consider proven false means. Rather than me guessing, you could provide examples if you want me to make any effort to refute them. Otherwise I will point to the Wikipedia page which I believe backs up my previous comments[1]
>The media, the intelligence community, and most experts have treated the dossier with caution due to its unverified allegations, while Trump has denounced it as fake news...Some aspects of the dossier have been corroborated, in particular its main allegations that Putin and Russia actively favored Trump over Clinton and that many Trump campaign officials and associates had multiple secret contacts with Russians. However, many allegations in the dossier remain unverified. One allegation against Michael Cohen was dismissed by the Mueller Report, a court ruled that another of the claims was "inaccurate and misleading" and stated another claim was inaccurate. Goldman and Savage have described it as "deeply flawed". The Daily Telegraph has reported that anonymous sources believe Russian intelligence agencies may have sought to create doubt about the veracity of the dossier.
Look it up, it’s easy to find examples.
