WASHINGTON - Rank-and-file Republican lawmakers are protesting the tactics of tea party colleagues who demand that legislation to keep the government open also take away federal funding for Planned Parenthood.

Eleven GOP House freshmen say they support a short-term funding bill needed to guarantee the government won't shut down next week. But they oppose a shutdown confrontation over Planned Parenthood, which is under intense criticism for undercover videos that raise questions about its practice of supplying fetal tissue for scientific research.

A letter by New York freshmen Ryan Costello and Elise Stefanik promises to "avoid the mistakes of the past" - a reference to the GOP-sparked 2013 shutdown over implementation of the new health care law.
