Woah:

In an escalation of the confrontation between the United States attorney in Manhattan, Preet Bharara, and Gov. Andrew M. Cuomo over the governor’s cancellation of his own anticorruption commission, Mr. Bharara has threatened to investigate the Cuomo administration for possible obstruction of justice or witness tampering.

The warning, in a sharply worded letter from Mr. Bharara’s office, came after several members of the panel issued public statements defending the governor’s handling of the panel, known as the Moreland Commission, which Mr. Cuomo created last year with promises of cleaning up corruption in state politics but shut down abruptly in March.
