New York State Senate
Maziarz was first elected to the New York State Senate in 1995 and was a "power-broker" in Western New York Republican circles during his term in office. In January 1997, Maziarz was named Chairman of the Senate Aging Committee, a post which he held through the 2001-2002 session. At various points Maziarz served as chairman of the Tourism, Recreation, and Sports Development Committee, Labor Committee, and Energy and Telecommunications Committee; he was also a member of the Rules; Higher Education; Crime, Crime Victims, and Corrections; Environmental Conservation; and Transportation committees. He voted against same-sex marriage legislation on December 2, 2009; the bill was defeated. In 2011, Maziarz voted against a similar bill, the Marriage Equality Act, which the Senate passed 33-29. In July 2014, "amid reports that his office under investigation by a federal prosecutor," Maziarz announced that he would not seek re-election to the Senate that fall.
Corruption charges and guilty plea
In 2014, a team of investigators of the Moreland Commission to Investigate Public Corruption issued subpoenas that showed that "Maziarz's campaign had failed to disclose $147,000 in contributions and $325,000 in spending." A review of Maziarz's bank records showed "personal, nonpolitical expenditures" made from campaign accounts; from 2007 through 2013, investigators found that credit and debit cards associated with Maziarz's campaign funds were used to pay "$28,000 at stores like Pier 1 and Michaels; $7,500 at Shutterfly, the photo-printing site; and $7,850 for reading material, including a stop at a Borders store at Kennedy Airport." In March 2017, Maziarz was charged with five felony counts of filing false campaign expenditure reports. The New York State Attorney General's Office charged that Maziarz had made the reports to illegally conceal $100,000 in payments to a former aide who had departed from his position amid accusations of sexual harassment. Maziarz pleaded not guilty. On March 20, 2018, Maziarz pleaded guilty to a misdemeanor as part of a deal allowing him to avoid trial for five felony counts. Maziarz was fined $1,000 "after admitting to one count of offering a false instrument for filing as part of a scheme to cover up payments from his political campaign to Glenn Aronow, a former staffer who had been accused of sexual harassment."
