A man sentenced to 20 years in prison for laundering money for the Zetas drug cartel has been arrested for attempting to bribe a federal judge.

FBI agents charged Francisco Colorado Cessa, his son and a business associate Friday.

Colorado Cessa argued at his sentencing Thursday that while he participated in a scheme to launder drug money by buying and selling racehorses, he spent his own money not the Mexican cartel's drug money. His business associate, Ramon Segura Flores, testified on his behalf.

Judge Sam Sparks gave Colorado Cessa the maximum sentence.

U.S. Attorney Robert Pitman said in a statement that Segura, Francisco Colorado Cessa Jr. and his father offered the judge $1.2 million. Their attorney did not return a phone call Friday.
