Several Texas troopers said border security was given orders to push migrants back into the water.
The Texas Department of Safety said the allegations are under internal investigation.
Migrants crossing the Rio Grande from Mexico walk past large orange buoys deployed by Texas border security.
According to the Chronicle, Wingate urged for policy changes to improve safety for the migrants, including removing the order to deny migrants water.
A spokesperson for the Texas Department of Safety did not immediately respond to a request for comment.
