Gotbaum said in a public statement, “Having known Kirsten since before she became a Congresswoman, I know she is very bright, capable and extremely hard-working. Kirsten learned quickly now that she represents the entire state and has adapted very well to her role. She continues to be a strong and dedicated leader for New York's families, fighting for equal pay, quality and affordable health care, and the best educational opportunities for our children. I know that Kirsten Gillibrand will stand up for all New Yorkers and I am proud to support her."

The statement comes three days after Representative Carolyn Maloney of Manhattan announced she will not challenge Gillibrand. Maloney, who, like Gotbaum, is from Manhattan, has not said who she’ll support for senate.

Representative Jose Serrano is also not running, nor committing to supporting Gillibrand just yet.
