The Democratic senator Kirsten Gillibrand is running for president.

At a taping of The Late Show with Stephen Colbert Tuesday evening, Gillibrand shared that she was officially joining the race for the White House. Announcing that she was assembling an exploratory committee and would soon be on her way to Iowa, she told Colbert she was running as a mom as she outlined key parts of her platform:

“I’m going to fight for other people’s kids as hard as I’d fight for my own, which is why I believe healthcare should be a right, not a privilege; it’s why I believe we should have better public schools for our kids because it shouldn’t matter what block you grew up on; and I believe that anybody who wants to work hard enough should be able to get whatever job training they need to earn their way into the middle class.”

Gillibrand is a strong critic of Donald Trump and has worked to block many of his priorities. She was also an early advocate for abolishing the Immigration and Customs Enforcement agency (Ice) and has been vocal about advancing women’s rights – earning a title from 60 Minutes as the “#MeToo Senator”.

She has stated that the former president Bill Clinton should have resigned, and was among the first to call out Senator Al Franken following multiple accusations of sexual misconduct. George Soros, a prominent Democratic funder, said that, as a result, she wouldn’t be getting his support. Soros called her an “opportunist” who spoke out against Franken to bolster her political brand.
