told NHPR that he was uncertain that the override would be successful.

"It really depends who shows up," he explained. "If all our supporters show up, we get it overridden. If as in other House sessions, we see they haven’t show up, it’s going to be difficult to bring it forward and be successful."

The Professional Fire Fighters of New Hampshire (PFFNH) has accused O'Brien of "using Republican presidential candidates as lobbyists to further his personal anti-worker agenda."

"The speaker is orchestrating a dog and pony show, using GOP presidential candidates to generate support for a right-to-work bill that doesn't have support in the New Hampshire House and would do nothing more than erode the rights of New Hampshire workers," PFFNH president Dave Lang said in a media advisory.
