Opponents of a controversial pipeline project want Bernie Sanders and Hillary Clinton to weigh in on the issue.

Members of the group "Stop the Algonquin Pipeline Expansion" (SAPE) held a vigil in Chappaqua near Clinton's home on Monday. Protesters say they fear the planned pipeline is so close to Indian Point that it increases risk to the Hudson Valley.

The group wants the subject to be discussed at the New York Democratic primary debate on Thursday night.

Clinton, the Democratic presidential front runner, sponsored legislation while she was a senator to require an independent safety assessment of the plant.

Her rival, Sanders, says he wants the nuclear power plant shut down. "We're just trying to get attention to this issue because nobody has answered the question yet. This is the only place in the entire country with the pipeline close to a nuclear power plant," says SAPE vigil organizer Susan Rubin.
