I saw this about the time it came up. She is pushing this bill in response to legislature on women's access to birth control and/or being required to learn about abortion, make a waiting period, and be taught about her body (possibly the forced vaginal ultrasounds as well). She's deliberately turning it around on the men in congress to illustrate the absurdity of these laws.
Edit: In case someone is interested.
“Any action in which a man ejaculates or otherwise deposits semen anywhere but in a woman’s vagina shall be interpreted and construed as an action against an unborn child.” — Text from the amendment proposed by Oklahoma State Senator Constance Johnson as a protest to the state’s controversial “personhood” bill (currently being debated in the State Senate) which would force women to listen to the heartbeat of the fetus before going through with an abortion"
Edit: For more information, it doesn't look like it passed. This lady's amendment appears to have been added on to the Personhood bill in the first place, and she later voted to table it (in effect, killing it).
