[EX Q]: After previously withholding his endorsement , U.S. Sen. John Cornyn , R-Texas , said Sunday he 's supporting Ted Cruz for re-election in 2018 . 
While Cornyn made a pitch for the latest proposal , known as Graham-Cassidy , Cruz continued to assert he was undecided -- and was even more explicit at one point , saying Senate leaders still do n't have his vote . 
In a joint session with Cruz at the Texas Tribune Festival , Cornyn called the junior senator "enormously constructive" in the Senate and pledged to support him as he seeks a second term . 
Cornyn said he recently had breakfast with Cruz and they agreed it was important to set aside their differences -- mainly on tactics , not policy -- in the wake of Hurricane Harvey . 
"I think it 's really important , particularly in light of the challenges brought by this huge natural disaster , that we stand together as a Texas delegation and there 's no space between Sen. Cruz and me when it comes to doing work for our state ," Cornyn said . 
Cruz said Graham-Cassidy has some "very good elements" but does not do enough to lower health insurance premiums . 
The authors took the changes but removed them a day later , Cruz said . 
Cornyn had previously declined to endorse Cruz for re-election , saying he was "not going to get involved in any primary races , particularly with my colleagues in the Senate ." 
And Cruz refused to back Cornyn when he was seeking re-election in the 2014 primary . 
"Right now they do n't have my vote , and I do n't think they have Mike Lee 's either ," Cruz said . 
Watch Smith 's full interview with Cornyn and Cruz below . 
In 2018 , Cruz is facing a challenge from U.S. Rep. Beto O'Rourke , D-El Paso . 
Cruz has been generally tight-lipped about O'Rourke , but he went further than usual at the festival while responding to a question about his opponent . 
"I do n't think Texans want a far-left Democrat in the Senate ," Cruz said .

[EX Q]: Keith Perkins  got the phone alert and later heard the sirens going off in  his  southeast Alaska hometown of Sitka.
 He  said people on Facebook were chattering back and forth about whether this was real or not and what they should do.
Given the magnitude of the earthquake   Perkins  said  he  thought it best to head to the high school  a tsunami evacuation point  even though in the past  he  felt  his  home was at a "high-enough spot."
"I figured I'd probably just better play it safe "  he  said.
In Seward  at the southern end of Alaska's Kenai Peninsula  residents retreated to higher ground or left on the only road out of the city  fire chief Athey said. He described  it  as a controlled evacuation and compared  it  to folks driving home from a holiday fireworks show.
