(CNN) Democratic Sen. Kirsten Gillibrand said she is "definitely thinking" about running for president in 2020 and will announce a decision in the near future.

"I'm definitely thinking about it, of course. And I'm going to think about it over the holidays with my children and my husband, and I will make a decision soon," Gillibrand said on CNN's "The Van Jones Show," airing at 7 p.m. ET on Saturday.

"This is sort of where my faith drives me. I do believe in these moments of great darkness — of great pain, of great suffering, of great division, of great hatred — that all of us are called to do something ... to restore what is good in our world," Gillibrand said. "And I feel very called at this moment to fight as hard as I possibly can to restore that."

When asked why she might not run for the presidency, Gillibrand said she wants to make sure her family is ready for an "arduous and serious process."

Gillibrand joins a growing field of potential Democratic candidates looking to toss their hats in the ring for 2020. According to a CNN poll this week , the top contenders include former Vice President Joe Biden, Vermont independent Sen. Bernie Sanders and Texas Rep. Beto O'Rourke.
