Sen. Kirsten Gillibrand has officially entered the 2020 race for president.

In a campaign video released Sunday, the New York Democrat said the country needs "a leader who makes big, bold, brave choices."

In January, Gillibrand said in an appearance on “The Late Show with Stephen Colbert” that she was filing the paperwork necessary to launch an exploratory committee, which would enable her to raise money for a White House run.

“I'm going to run as president of the United States because, as a young mom, I'm going to fight for other people's kids as hard as I would fight for my own,” she said Tuesday.
