Zephyr Teachout has filed paperwork to run for New York State Attorney General in 2022.
Teachout said she would seek the office if Attorney General Letitia James ran for governor.
On Friday the latter happened, which prompted Teachout to file paperwork.
She unsuccessfully ran for governor in 2014 against then-Governor Andrew Cuomo.
Others are expected to enter the race, and even a few more Democrats is possible.
