. Tuckman is a Buddhist. He ran the mayoral campaign for Ollie and was the advisor to Oliver Queen while he was Mayor. He knew Oliver was Green Arrow
Later, when Nudocerdo
had revealed that Ollie had funded the Outsiders
and called for a re-election, Tuckman went to Nudocerdo and pretended to have been defeated and got the position of Head of City Council. Since there was no acting Deputy Mayor when Ollie stepped down, Tuckman became the new mayor of Star City.
