SANTA FE, N.M. — New Mexico attorney general’s office is probing deeper into the campaign finances of embattled former Sen. Phil Griego with the consent of a district court judge.

Court documents filed this week show an investigator with the New Mexico attorney general’s office obtained a search warrant to access bank records for a political action committee that Griego allegedly helped create. Investigator Mark Pinto says Griego moved money between his campaign fund and the committee without disclosures required by law.

Thomas Clark, an attorney for Griego, said Thursday that state prosecutors are placing an undue amount of scrutiny on the ex-Senator.

The campaign finance case was referred to the attorney general’s office by the Office of the Secretary of State that oversees campaign finance disclosures.

Separately, Griego was ordered in July to stand trial in a corruption case linked to his private commission on the sale of a state-owned building.

He has pleaded not guilty in that case to charges of fraud, bribery, perjury, tampering with public records and possible violations of public ethics and financial disclosure statutes.

Clark said he was in the process of reviewing documents related to the new search warrant and declined to address specific allegations of probable cause.

“It seems from our perspective that an undue amount of security is being placed in Phil Griego and Phil Griego alone,” he said.
