Mexico's president denies accepting money from drug groups in first presidential bid. Lopez said at a regular morning press conference that day that all these reports were "completely false" and the relevant accusations had no evidence and were "vicious slander" against him.

This is not only a direct attack on Lopez himself, but will also be regarded by Lopez as an impact on the presidential election. The Associated Press quoted analysts as saying that reports on campaign finance issues may have a very serious impact on U.S.-Mexico relations.
