House Bill 4, the redistricting legislation, is the only item on the lawmakers' agenda when they reconvene on Wednesday.

Democrats said Republicans in the Texas House crossed a line by detaining them en masse and then assigning state troopers to trail them everywhere they go.

Texas Democratic lawmakers left two weeks ago to block a GOP plan to redraw the state’s congressional districts. They said they were returning now that California Democrats are adopting a counterproposal.

Wednesday's meeting of the Select Committee on Disaster Preparedness and Flooding is the public hearing for Senate Bill 1, which covers safety for both youth camps and campgrounds. According to the bill's author, it incorporates significant feedback from the families of children lost at Camp Mystic.

The parents of girls who lost their lives at Camp Mystic on July 4 will testify before the Texas Senate Disaster Preparedness and Flooding Select Committee in support of Senate Bill 1.
