Sen. Kirsten Gillibrand (D-N.Y.) was almost goaded into announcing a presidential campaign on The Late Show with Stephen Colbert in November. Now, she's taking to the show again, and reportedly has a new message in mind.

The junior senator is planning to form a 2020 exploratory committee and reveal her intention to run on Tuesday's episode of the CBS show, CBS News reports. But that report comes just hours after another source told The Associated Press that Gillibrand will announce on a trip to Iowa this weekend.

Just two weeks before her November Colbert appearance, Gillibrand said she'd "serve [her] six-year term" after winning Senate re-election last year. She then told Colbert she'd give the presidency a "long, hard thought." She's since reached out to Wall Street executives, hired what appears to be a campaign staff, and leased what could be a campaign headquarters near Albany, New York.

Gillibrand has long been considered a possible 2020 Democrat, and would join fellow Sen. Elizabeth Warren (D-Mass.) on the playing field. Sens. Kamala Harris (D-Calif.) and Corey Booker (D-N.J.) are thought to be considering runs, while Rep. Tulsi Gabbard (D-Hawaii) and a handful of other Democrats have already made it official.
