HOUSTON -

Dozens of nuns gathered in southwest Houston to board a bus headed to Austin Wednesday morning.

It is all part of the "Nuns on the Bus" rally that will advocate on behalf of the working poor.  

The 70 nuns that left the Archdiocese of Galveston-Houston Wednesday will be joining nuns from around the state to advocate for healthcare for all Texans.

"There are groups coming from Dallas, San Antonio and we're all going to get together and have a rally and visit our legislators and talk about the need for Medicaid expansion in Texas," said Sister Margaret, from Sister Charity of the Incarnate Word.

The nuns said the issue of health care and helping the uninsured is close to their hearts.

They have been praying about this rally and gathering support for months.

The group is urging state officials to accept federal funds and are seeking support for Senate Joint Resolution 8, which was introduced by State Senator Rodney Ellis.
