Kirsten Gillibrand has built her career on a simple premise: if something is broken, fix it, even if powerful people don’t want you to. That fearlessness has made her one of the Senate’s most effective reformers.

As a junior senator, Gillibrand took on the Pentagon over military sexual assault, refusing to back down despite fierce opposition. She was a leading sponsor of the law guaranteeing 9/11 first responders get the healthcare they need. She helped win federal paid family leave for federal workers and championed it nationwide. And she’s fought relentlessly to protect access to reproductive healthcare.
