The Federal Emergency Management Agency’s acting leader has adamantly defended the federal government’s response to historic flooding in Texas earlier this month, saying lawmakers’ attacks on the agency’s actions were unwarranted.

Nim Kidd, chief of the Texas Division of Emergency Management and representatives from the Upper Guadalupe River Authority are expected to testify.

While search efforts continue for the few missing in the Texas Hill Country, state officials met to evaluate the response to the deadly July 4 flood.
