Texas flooding updates: Over 130 dead as flash flood threat increases in Texas

Sen. Ted Cruz, R-Texas, called the flooding aftermath at Texas' Camp Mystic -- where at least 27 campers and counselors died amid flooding -- "the most horrible thing I've ever seen."

"The water rose 7 and 8 feet … the cabins are cleaned out, all of the furniture has been pulled out by the current," he told Lindsey David on ABC News Live Prime after touring the campground. "It's heartbreaking."

Cruz said his daughters have gone to summer camps in Kerr County, in Texas' Hill Country, for 10 years and said just last week, his wife had picked up their youngest daughter from camp.

For now, the focus remains on search and rescue, Cruz said, but in the coming weeks and months, he said he hopes to take a look at the timeline of exactly what happened and when warnings went out to see if something could have been done better.

"There's no doubt, any one of us, if we had a time machine and we could step in it right now, we would run to those girls' cabins and pull them out of the cabins before the floodwaters rose," he said. "And so it's worth asking, what could have been done differently?"

Cruz, who was on a pre-planned trip with his family in Greece on Friday when the floodwaters rose, said he was working the phones almost immediately, calling the governor, other state officials and even President Donald Trump.

"You know, look, people love to play politics. I was overseas on a family vacation when this happened. I was almost immediately on the phone," Cruz said, adding, "And then I booked a flight and came back."

Cruz said he left Sunday morning and arrived in Texas on Sunday night.

Over 100 people have died from flooding in Texas.

The vast majority of the fatalities -- 84 -- were in Kerr County.

Deaths have also been confirmed in Travis, Williamson, Burnet, Tom Green and Kendall counties.

There have been over 850 high-water rescues, Texas Sen. Ted Cruz said.

"Texas will come through this," Cruz said at a news conference.

Questions have swirled around if there was enough warning and enough staffing for the early Friday morning floods in the wake of the Trump administration's job cuts to the National Oceanic and Atmospheric Administration.

But NOAA confirmed that the National Weather Service's Austin/San Antonio office had five meteorologists working the severe weather event as part of its "surge staffing" protocol. It is normally staffed with two.

NOAA also said the NWS had forecast briefings Thursday morning, issued a flood watch Thursday afternoon and then issued flash flood warnings on Thursday night and early Friday. This gave "preliminary lead times of more than three hours before flash flooding conditions occurred," NOAA said in a statement.

White House press secretary Karoline Leavitt said on Monday, "Blaming President Trump for these floods is a depraved lie, and it serves no purpose during this time of national mourning."

Texas Sen. Ted Cruz said Monday, "Some people [are] engaging in partisan games and trying to blame their political opponents for a natural disaster."

"I think most normal Americans know that's ridiculous and I think this is not a time for partisan finger pointing and attacks," he said.

“I think it is reasonable, over time, to engage in a retrospective and say, at every level, what could have been done better, because all of us would want to prevent this horrific loss of life," he said.

Chuck Schumer, the Senate's top Democrat, is calling for an investigation into whether cuts made to NWS had any correlation to the level of devastation.
