Rally for Mueller at Long Wharf in Sag Harbor

Protesters gathered at the windmill on Long Wharf in Sag Harbor on Thursday afternoon in support of Robert Mueller, the special counsel named by the Department of Justice to investigate Russia's involvement in the 2016 federal election. Mr. Mueller's status was thrown into question when President Trump fired Attorney General Jeff Sessions.

The rally, one of 500 nationwide promoted by the activist group MoveOn, drew an estimated 50 or 60 people, many of whom held signs reading "No One's Above the Law." It was organized here by Wendy Wachtel of North Haven, who had been hoping to take a political breather after canvassing to bring out voters for the midterm elections.

"I just felt it was too important," Ms. Wachtel said. "I was exhausted and ready to lie down and watch bad TV, and then this happened and I was like, 'Oh, no, no, no!' "

Nick Gazzolo, the president of the Sag Harbor Partnership, who was among the protesters, said, "I don't think the president, no matter who they are or from what party, should be able to control investigations into their activities." He was referring to President Trump's firing Mr. Sessions last week and subsequently appointing an ally to replace him.

Edwina von Gal, founder of the Perfect Earth Project, explained why she was at the rally. "You just wouldn't want to feel like you didn't make an effort — I think I share that with everyone here."
