As expected, Western New York political operative Kristy Mazurek will run in a democratic primary for New York’s 143rd Assembly seat. Mazurek officially announced her candidacy Wednesday evening.

“Everybody in Albany, in that assembly chamber, knows who Kristy Mazurek is. That’s for certain.,” she said.

Mazurek was the treasurer of the WNY Progressive Caucus, a political action committee connected to former Erie County Democratic chairman Steve Pigeon. Complaints of election law violations committed by the PAC led to a federal and state probe.

Sources said the scope of the probe appeared to have expanded and about a month ago the attorney general convened a special grand jury.

“I have been in compliance with everything investigators have asked of me over the last three years,” Mazurek said.

While there’s a good chance the results of that grand jury could surface before the primary, Mazurek said she’s not concerned. According to a source, she has a non-prosecution agreement with investigators.

“I know the person that I am. I’m not perfect but I am the most qualified person running for this seat,” she said.

She does know the district. In fact, Mazurek worked in the 143rd Assembly office for Dennis Gabryszak.

She was one of seven female former staffers who sued Gabryszak for sexual harassment. A judge threw out her case but she’s currently appealing it.

“I was a victim of all the bad things that have happened in Albany and I want to make sure I go and represent the people of this community, as I have and as my family has for decades, in the right way,” Mazurek said.

She’s running against the democratic party’s endorsed candidate, University at Buffalo law professor Monica Wallace. Village of Lancaster trustee Russ Sugg has been endorsed by the Republican party.
