Federal agents are testifying against a West Texas lawyer and former Carnegie Mellon University trustee accused of conspiring to launder drug money.

Marco Antonio Delgado is accused of devising a scheme to launder up to $600 million for the now disbanded Milenio cartel from 2007 to 2008.

Delgado's trial is continuing Wednesday.

Agents have previously testified that Delgado was arrested with $1 million and confessed it was part of a "trial run" in the operation. Delgado's lawyer says he never knew it was drug money. Instead, he claimed associates of Lilian De La Concha, the ex-wife of Mexico's ex-president Vicente Fox, asked him to help them move money from an inheritance.

Delgado gave a $250,000 endowment for a Carnegie Mellon scholarship named after him to assist Hispanic students.
