The New York Times reports this morning that Preet Bharara, the U.S. Attorney in Manhattan, has sent a letter warning the Cuomo Administration of a possible investigation for obstruction of justice and witness tampering.

U.S. Attorney Bharara has been investigating the shutdown of the Moreland Commission and other corruption cases in New York since April. The letter was read to the times and reads in part:

“We have reason to believe a number of commissioners recently have been contacted about the commission’s work, and some commissioners have been asked to issue public statements characterizing events and facts regarding the commission’s operation. To the extent anyone attempts to influence or tamper with a witness’s recollection of events relevant to our investigation, including the recollection of a commissioner or one of the commission’s employees, we request that you advise our office immediately, as we must consider whether such actions constitute obstruction of justice or tampering with witnesses that violate federal law.”

According to the Times, a spokesman for the Governor did not immediately respond late last night, and a lawyer for the commission declined to comment on the letter.

The Times reported last week that Governor Cuomo’s office had deeply compromised the panel’s work, objecting when it focused on groups with political ties to Cuomo or on issues that might reflect poorly on him.
