PROBLEM: (CNN)  Iraq war veteran Taylor Winston  became a hero on the night of the mass shooting in Las Vegas after  he  used a stranger's truck to rush critically wounded victims to the hospital.
Now  Winston  has a new truck of  his  own.
An Arizona car dealership rewarded  him  Monday with a free  customized Ford F-150 in appreciation for  his  bravery and quick thinking on October 1  when  Winston  made two trips to the hospital while officials were still scrambling to get ambulances to the concert venue.  Winston  credited  his  military training for helping  him  keep a "cool head."
"It was still quite scary  but we just knew they (the victims) had to get to the hospital immediately "  Winston  told CNN's Anderson Cooper last week. "No ambulances were immediately available. There was far too many casualties for anyone to handle."

PROBLEM: Trump took to Twitter on Tuesday to claim that Tennessee Republican helped "give us" the nuclear deal with Iran negotiated by President Barack Obama's administration. Earlier this month  he claimed that  Corker  is "largely responsible for the horrendous Iran Deal!"
 Corker  the chairman of the Senate Foreign Relations Committee   was in fact a vehement critic of the deal that emerged from international negotiations in the summer of 2015. After the deal was unveiled   he  wrote in an op-ed for The Washington Post that "Congress should reject this deal and send it back to the President."
 Corker  plotted efforts to block the deal  banding with Republicans -- and even some Democrats -- in an attempt to block the deal.
The following month   Corker  did just that  joining with the bipartisan group to vote against the deal. A procedural vote to move forward a resolution to reject the nuclear deal fell shy of the required 60-vote threshold.
Even before that vote   Corker  helped push through the legislation that would ultimately grant Congress powers to review the deal  which the Obama administration contemplated approving without congressional oversight.
 Corker  said such an attempt would be "a direct affront to the American people and seeks to undermine Congress' appropriate role" in a March 2015 letter to Obama.
 Corker 's calls for congressional review of the nuclear deal that was still being negotiated in the spring of 2015 ultimately led to the Iran Nuclear Agreement Review Act  which Obama ultimately signed despite initially opposing the measure.
That could be what White House press secretary Sarah Sanders was referring to on October 10 when she claimed: " Sen. Corker  worked with Nancy Pelosi and the Obama administration to pave the way for that legislation and basically rolled out the red carpet for the Iran deal  and those are pretty factual."
 Corker  defended the bill against that criticism in September 2015  noting that the legislation "actually took power back from the president."
"Without it  he could have unilaterally implemented the deal immediately. The President never would have been forced to submit the agreement to Congress and there would have been no review and no debate on this critical national security issue "  Corker  said then.
Trump's criticism of  Corker  on the Iran deal is also curious given that Trump initially considered  Corker  as a candidate for vice president and later secretary of state  in large part due to his foreign policy chops.

SOLUTION: Corker

PROBLEM: The Air Force says a mistake allowed  Devin Patrick Kelley  to buy guns. On  Sunday Kelley  opened fire on a small church in Sutherland Springs  Texas.
"Initial information indicates that  Kelley 's domestic violence offense was not entered into the National Criminal Information Center database by the Holloman Air Force Base Office of Special Investigations " said Air Force spokesperson Ann Stefanek in an email.
 Kelley  purchased four guns over a four-year period beginning in 2014  according to federal officials; all those purchases were made after  his  court-martial conviction and discharge.
"This was mishandled by the Air Force Office of Special Investigations at Holloman Air Force Base in New Mexico  where  Kelley  was serving when he was arrested " Tom reports. "An investigation is now underway  and the Air Force is taking it very seriously  said the source."
Retired Col. Don Christensen  who was the chief prosecutor for the Air Force at the time of  Kelley 's general court-martial  tells NPR that the case was serious.
 Kelley  accepted a deal  pleading guilty to a charge of assault on  his  wife and to a charge of "intentionally inflicting grievous bodily harm" on the child  Christensen says. His crimes were punishable by up to five years confinement (the military equivalent of a prison term). As part of the deal   Kelley  received an 18-month cap on his confinement and was ultimately sentenced to 12 months.
 Kelley 's punitive discharge â a bad conduct discharge â did not prohibit him from owning a gun  as a dishonorable discharge would have.
 Kelley 's conviction qualified under both categories  Christensen says.
NPR's Martin Kaste reports that Academy Sports & Outdoors  a store that sold  Kelley  guns  says it ran a background check on  Kelley  twice in the past two years.  Kelley  passed each time   the company  says.
If  Kelley 's convictions were never uploaded into the system  that could easily explain how  he  passed. But even if they had been uploaded  there might still have been trouble getting information into the right hands â there's a sort of language barrier between military and civilian justice systems  Christensen says  with different terms for the same kinds of crimes. If the military described a general court-martial for assault  with a sentence of one year  the civilian authorities might "never realize" it was a domestic violence conviction punishable by five years  he says.
In general  there are some "gaping holes" in the current background check system  as NPR's Danielle Kurtzleben reported last year  which can allow people who should fail background checks to buy guns anyway. And if  Kelley  had purchased a gun from a private seller  he wouldn't have had to pass a background check at all  Martin notes.
Meanwhile  Texas Gov. Greg Abbott says  Kelley  applied for a license to carry a gun and was rejected  Martin reports. He notes that Texas requires a background check but also has additional training and tests that  Kelley  may not have completed.
