Trump surveys damage in Texas after floods kill 120 and leave 160 missing

 

Donald Trump is visiting flood-ravaged central Texas, where 120 people were killed last weekend.  Another 161 are still missing

 The US president and First Lady Melania Trump are expected to meet with first responders and families in Kerrville

 Their visit comes as questions mount over the response from authorities, and what warnings residents received

 As the BBC's Bernd Debusmann Jr writes, the president is likely to face tough questioning about whether enough was done to alert people of the dangers

 Last weekend, deadly storms ravaged central Texas, with several months' worth of rain in a few hours.  River levels rose, submerging homes, roads and cars
