Democratic star Beto O’Rourke will decide whether to run for president by the end of the month, he told Oprah Winfrey on Tuesday during an interview in Times Square.

The former Texas congressman told Oprah that he’s been “thinking about running for president” and that he was “excited at the prospect of being able to play that role.”

As Winfrey — who has shot down suggestions that she’ll throw her hat in the 2020 ring — prodded O’Rourke to run, he said the decision would hinge on his wife and three children.

“By God, when are you going to know the answer?” asked Winfrey.

O’Rourke replied he hoped to come to a conclusion “really soon,” hopefully by the end of February.

During his failed bid to unseat Republican Sen. Ted Cruz last fall, O’Rourke raised $80 million and built a national Democratic following.

In the interview for Winfrey’s TV show “Oprah’s SuperSoul Conversations from Times Square,” O’Rourke also said he would legalize Dreamers, give their parents legal status and increase immigration quotas, CNN reported.

He called President Trump’s southern border wall push “a racist response to a problem we don’t have.”

“It seeks emotionally to connect with us, with voters — to stoke anxiety and paranoia, to win power over ‘the other’ on the basis of lies that vilify people,” O’Rourke said.

The lineup for the taping of Winfrey’s show Tuesday also included actors Bradley Cooper and Michael B. Jordan and philanthropist Melinda Gates.

The interview will air on Winfrey’s network, OWN, Feb. 16.
