Former U.S. Congressman and Staten Island Borough President Guy Molinari has not been shy about voicing his criticism of GOP presidential hopeful Newt Gingrich, telling the Staten Island Live on Tuesday that the former Speaker of the House is evil and may not be able to contain himself when Gingrich arrives in the borough for a town hall meeting this weekend.

Molinari's feud with Gingrich stretches back to the 1980s, when then men served in the U.S. House of Representatives together. Molinari, a Republican, represented New York's 14 and then 17 district's between 1981 and 1989, before serving as the Staten Island Borough president between 1990 and 2001.

The thought that this man could be president of the United States is appalling, Molinari told the source. He's got all kinds of baggage.

Molinari, who is a leading member of Mitt Romney's presidential campaign, claims Gingrich is responsible for removing him from his position as the ranking Republican on the Investigations and Oversight subcommittee of the Public Works and Transportation Committee, going against a written agreement stating he was not to do. Molinari said that double-cross effectively ended his career in the U.S. House, leading him to run for borough president.

This guy is evil.  He's an evil person, Molinari said. While he told the source he is tempted to do something when Gingrich is in the area over the weekend -- he did not specify what -- he said likely will not attend the town hall event.

The event was planned in Staten Island, New York's most conservative borough, following his recent leap in the polls after months of ranking in the single-digits. Even when it seemed as though Gingrich's campaign would not last through the summer, Molinari was outspoken in his opposition of his former colleague.

Newt Gingrich as president of the United States? That cannot happen,  Molinari told the New York Post in May.

The Gingrich campaign has not responded to Molinari's comments.
