A man at the center of the Cameron County "cash for court favors" scandal took the stand against former district attorney Armando Villalobos.
Villalobos is under trial for a nine-count federal racketeering indictment, for which he faces 20 years in prison.
Openings arguments before U.S. District Court Judge Andrew Hanen started on Monday morning.
Prosecutors called former 404th State District Judge Abel Limas as their first witness against Villalobos.
Limas pleaded guilty to his role in the scandal but is still awaiting sentencing.
During his testimony, the former judge told jurors he once blew a substantial part of a bribe watching a boxing match in Las Vegas that Villalobos also attended.
During his testimony, Limas told jurors that he voluntarily surrendered his law license following his guilty plea in the scandal.
The former judge testified that he took numerous bribes for courtroom favors.
Limas described the actions as, "helping friends."
Among those "friends" was Armando Villalobos, Limas testified.
Limas testified that he had once considered himself to be a father figure, mentor and friend to Villalobos.
Prosecutors contend it was a lucrative relationship earning Limas tens of thousands of dollars.
De La Hoya Fight
Limas testified that the money he made by taking bribes never lasted long.
The former judge testified that he blew a lot of the money on trips to Las Vegas.
one of those trips included one to see a May 2007 boxing match between Oscar De La Hoya and Floyd Mayweather.
Limas testified that Villalobos and several others were also there at the match.
