House party
In 2008 Mascaro was one of five state representatives filing a bipartisan ethics complaint against a fellow Republican for allegedly bribing his opponent during a primary election. Shortly later, an unrelated report by a female intern about Mascaro was leaked, with the suggestion of improper conduct. Speaking to the media Mascaro dismissed the report, arguing the story was retaliation by House party leadership, who had already labeled Mascaro a "dissident Republican."
