It certainly takes more than a newspaper article. Again, I have a lot of respect for journalists, but I can't rely on a newspaper article.
By the way, the issue involved many implications, but none of that was confirmed by this article. First, it is not clear whether the money was used for the candidates' campaigns. The article does not say so. Even if you believe the article, you don't know whom the money went to or what it was used for. Essentially, we're talking about what I would call attempts at bribery or buying influence. Those are not necessarily attempts to influence the election.
