By Ted Hesson and Maria Alejandra CardonaQUEMADO, Texas (Reuters) -Hundreds of protesters from around the U.S. flocked to a Texas border town on Saturday to vent over illegal immigration and show support for former President Donald Trump at a rally that blended border politics with religious rhetoric. At the rally in Quemado, Texas, vendors sold shirts, flags and hats promoting the Republican former president while conservative speakers touted conservative Christian values and criticized the border policies of President Joe Biden, a Democrat. His critics worry such policies and events such as a convoy that preceded the rally could stoke tensions. Eagle Pass, 20 miles (32 km) south of Saturday's rally, has achieved national prominence in recent months. The "Take Our Border Back" protest began with a vehicle convoy from Virginia that rolled into Quemado on Friday night.
