A bill to ban cities, counties and other local governments from doing business with Planned Parenthood is on its way to Gov. Greg Abbott.

The Senate voted 20-11 Friday to approve a House-added amendment to Senate Bill 22, but only after the bill's author changed her mind twice about how to proceed.

Sen. Donna Campbell, R-New Braunfels, moved Thursday to agree with an amendment added by the House, then decided to seek a conference committee after Sen. Jose Menendez, D-San Antonio, questioned the meaning of the House addition, which said the bill "may not be construed to restrict a municipality or county from prohibiting abortion."

After consulting with other Republicans, however, Campbell returned to the Senate on Friday and said it was more expedient to leave the amendment alone and send the bill to Abbott.

"I feel this amendment is a circular sentence structured with a double negative that does absolutely nothing," Campbell said, noting that cities and counties do not have the authority to ban abortion.

SB 22 seeks to ban local governments from any type of transaction — including sales, purchases, leases and donations of money, goods and services — with an abortion provider or its affiliates.

Sen. José Rodríguez, D-El Paso, said the bill would harm lives by limiting access to HIV tests, cancer screenings, contraceptives and other health care provided by Planned Parenthood clinics that do not offer abortions.

Sen Carol Alvarado, D-Houston, said Planned Parenthood has partnered with Houston on public outreach about the Zika virus and other health issues, "so it's not all about abortion."

But Campbell said those who oppose abortion should not have their tax money go toward organizations that provide abortions or affiliated clinics.

"This bill just simply prevents taxpayer dollars from being used to support, or prop up, any abortion providers," Campbell said.

SB 22 would ban Austin from continuing to rent a city-owned building at East Seventh and Chicon streets for a Planned Parenthood health center for $1 a year. The clinic, which does not provide abortions, served 5,153 patients with subsidized health care worth about $560,000 last year.

In addition, the Austin school district is researching whether SB 22 would scuttle a proposed middle school sex education curriculum that was developed by the Planned Parenthood League of Massachusetts.

A second abortion-related bill was sent to Abbott on Thursday when the House voted 84-67 to approve Senate changes to House Bill 16, requiring that doctors who perform abortions provide immediate medical treatment in the extremely rare event of a live birth during an abortion.
