In a letter delivered to Representative Nick LaLota of New York’s First Congressional District on April 3, more than 200 constituents complained that he had yet to hold a public “town hall” event. The letter said its signers had hoped Mr. LaLota would “a different kind of representative” than his predecessor, Lee Zeldin, who was largely inaccessible to the general public. Perhaps in response, the congressman scheduled a virtual town hall on Wednesday night.
