ICE agents stopped a Catholic nun on Sunday in McAllen.

Sister Letty was on her way to Mass at Our Lady of Sorrows Church. Agents detained her on the way. ICE gave no reason. She was let go later that same day.

The news spread fast in the Valley. South Texas is deeply Catholic. Church is a big part of life here. Seeing a nun stopped by agents on a Sunday was hard to hear.

Our Lady of Sorrows Church put out a post for the parish.

"We ask our parish family to please keep this religious sister Letty in your prayers," the church wrote. "Reports indicate that she was detained while on her way to Sunday Mass. We pray for her safety, peace, and strength during this difficult time, and we hope for a swift and just resolution that allows her to be released soon."

Sister Norma Pimentel heads Catholic Charities of the Rio Grande Valley. She said agents stopped Sister Letty Sunday morning. She called ICE to ask why. ICE did not call her back.

The Catholic Diocese of Brownsville said it needed more details before it could comment.

Two Valley members of Congress stepped in to help.

Rep. Henry Cuellar (D-TX28) called DHS Secretary Markwayne Mullin and Tom Homan.

"The order has been given for her to be released today instead of tomorrow, and she'll be home tonight," Cuellar said. "My office stayed engaged with the Department of Homeland Security throughout this process, and I appreciate everyone who helped make this possible. Thank you to all who kept her in your prayers. We're thankful for this good news."

Rep. Monica De La Cruz (R-TX15) also called Secretary Mullin.

"My office worked closely with the Department of Homeland Security, and I'm grateful they acted to resolve this quickly," De La Cruz said.

The two reps are from the Valley. They are from different parties. Both said Sister Letty was free by that evening.

Rep. Vicente Gonzalez (D-TX34) spoke out.

"This is just another effect of this Administration's hyperaggressive immigration policies in our communities," Gonzalez said. "They have now led to the targeting of nuns on their way to Sunday Mass. It is a far cry of the criminals they said they would detain and deport. I'm in touch with church officials and closely monitoring this situation. I urge for Sister Letty's immediate release."

ICE did not talk to news outlets. The agency gave no public reason for the stop.

Why she was stopped is still not known.

A nun was stopped by agents on a Sunday morning. Her church asked people to pray for her. Two members of Congress had to make calls to get her home.

For many people in the Valley, this is not just about one woman. It is about what it feels like when agents stop a nun on her way to church on a Sunday morning.

Sister Letty got home Sunday night.
