Media mogul Oprah Winfrey endorsed presumptive Democratic presidential nominee Hillary Clinton on Wednesday, calling Clinton’s White House run a “seminal moment for women.”

“I’m with her,” the OWN CEO said in an interview with Entertainment Tonight’s Nancy O’Dell.

“Regardless of your politics, it’s a seminal moment for women. What this says is that there is no ceiling,” Winfrey said. “That ceiling has gone ‘boom,’ you know? It says anything is possible when you can be leader of the free world.”

The Selma star also noted that it’s time that America, as a country, rally behind the idea of electing a woman as President of the United States.

“America, it’s about time we made that decision,” Winfrey said. “This is the truth. I really believe that that is going to happen.”

When given the chance to support a woman for president in Clinton in the 2008 Democratic presidential primary, Winfrey, instead, endorsed fellow Chicagoan Barack Obama.

“I’ve voted for as many Republicans as I have Democrats,” Winfrey said in Iowa in 2007, adding that her support for Obama was “very, very personal.”

Backing then-Senator Obama for president marked Winfrey’s first public endorsement of a politician.

“What I know is that for her to take the risk of stepping out of her comfort zone is extraordinary,” Obama said of Winfrey in response to her endorsement.

It was speculated that Winfrey would one day kick off her own presidential bid.

“I can tell you one thing you can be assured of in this lifetime: as long as I’m black, I will not be running for office,” she told Extra last year.
