Declaring that it was time for even a private person like herself to get personal, the 32-year-old star delivered a passionate speech about the role Planned Parenthood has played in her life from her first visit at the age of 15, reported Los Angeles Times.
"'Have you been to the gynecologist yet?' That was the question my mom asked me at 15 when I informed her about a change that I noticed in my body. I'm not the type to divulge facts about my personal life, but I feel that in the face of this current political climate, it is vital that we all make it our mission to get really personal.
Johannson then made a public plea to the new US President Donald Trump, saying she would support him if he would support her, her daughter, her family and all American women.
"President Trump, I did not vote for you. That said, I respect that you are our President-elect and I want to be able to support you.
"First, I ask that you support me, support my sister, support my mother, support my best friend and all of our girlfriends, support the men and women here today that are anxiously awaiting to see how your next moves may drastically affect their lives," she said.
