Glen Cove Mayor Reginald Spinello swore in Joseph Capobianco to the City Council on Tuesday before its regularly scheduled meeting.
Capobianco, a Republican, won a special election last month to fill the seat of Nick DiLeo, a Democrat, who died in April.
As the meeting opened, each City Council member and Spinello welcomed Capobianco, who is a partner with the Garden City law firm Reisman Peirez Reisman & Capobianco.
The new councilman faced a standing-room-only crowd, many of whom came to speak about the city's animal shelter.
"What a great turnout for my presence," Capobianco quipped. "It's a joke. It's a joke. Thank you very much for all coming."
Spinello thanked former City Councilman Anthony Jimenez, a Democrat, who was appointed in July to temporarily fill DiLeo's seat. Jimenez served in that role after several council members opposed appointing Capobianco, who had been Spinello's choice.
The swearing-in of a fourth Republican caps a multiyear effort to wrest control of the city from Democrats, who dominated the six-member council for 20 years.
