SANTA FE, N.M. — State prosecutors are asking a court to reject an unusual effort to call New Mexico Attorney General Hector Balderas as a witness at a high-profile corruption trial being prosecuted by his office.

Balderas is being listed as a potential witness as an October trial date approaches for former Sen. Phil Griego on allegations that he used his position as a state senator to profit from the 2014 sale of a state-owned building in downtown Santa Fe without proper disclosure.

Balderas spokesman James Hallinan on Monday described the maneuver as a “last ditch effort by Phil Griego’s defense attorney to delay the trial.”

Defense attorney Thomas Clark is listing Balderas as a trail witness and highlighting a $1,500 campaign contribution by Griego to the attorney general’s 2014 campaign.
