"Fifty-three percent of the people in this state who are women deserve for you to know exactly what you're voting for," Poore told delegates afterward.
"You had a chance to hear the bill verbatim, and you walked out on 53 percent of the people in this state," Poore added, referring to delegates who left House chambers while the bill was being read.
She said the legislation is "trampling on the rights of women."
The bill was amended Tuesday to set the sentence for doctors convicted of performing abortions after 20 weeks at one to five years in prison. The bill originally set an indeterminate sentence of not less than one year in prison.
The bill goes to the Senate, where indications are it is likely to have difficulty going through the committee process and reaching passage stage on the Senate floor with only 11 days remaining in the legislative session.
A statement from WV Free, an abortion rights group, called the bill "dangerous." The group said that according to the Center for the Disease Control and Prevention, there were seven abortions performed after 20 weeks in West Virginia in 2010.
"Excessive and unnecessary restrictions on abortion care hurt not just women but the practice of medicine," Margaret Chapman Pomponio, executive director of WV Free, said in the statement. "Every pregnancy is different and we cannot presume to know all of the circumstances surrounding a personal, medical decision to have an abortion.
"A woman and her physician should be trusted," she said. " It is a sad day in West Virginia when our political leaders are playing doctor."
The action came the same day a House committee in South Carolina advanced a similar measure -- one that would limit abortions to 19 weeks. Both bills resemble a law struck down in Arizona that the U.S. Supreme Court decided not to reconsider.
