Trump was flown in by helicopter together with the US's first lady, Melania, to among other things meet rescue personnel and people affected by the flood.
When they landed in Kerville, a city in the worst affected area where at least 96 people have died, they were received by Texas Governor Greg Abbott.
The search for more than 170 missing, including five girls who were at a summer camp, has entered its eighth day. But no person has been rescued this week, which increases the fears that the death toll may continue to rise.
Trump has shaken off all questions about what significance his cuts of federal authorities have had on the consequences of the natural disaster. Trump describes the flood as something that occurs once every hundred years and which no one could have predicted.
Criticism has been directed at local authorities for being able to be more proactive, for example with preventive evacuations. At the same time, questions are being raised about the national weather agency (NWS), which is responsible for weather warnings but which has been forced to make drastic cuts by the Trump administration.
