Attorney general candidate Zephyr Teachout made a last-minute campaign stop in Albany to reassert a promise to take on state corruption and to look deeper into the Cuomo administration. 

Teachout is questioning Andrew Cuomo's use of government for his own campaign.

Teachout, who lost the 2014 gubernatorial primary to Cuomo, brought up the conviction of former top aide Joe Percoco, Cuomo's use of the state helicopter, and most recently, the stalled opening of the Mario M. Cuomo Bridge -- where opponents were quick to say the governor pushed the opening for a photo-op ahead of his own primary election.

Teachout says it's the AG's job to examine any potential misuse of tax payer dollars.

"I will not hesitate to speak up for New Yorkers, be the poeple's voice, call out ethical or lapses in the executive branch -- where ever I see them," she said.
