Example Input: Even after Senate Republicans scrapped the vote on  the Graham-Cassidy bill  this week  lead  sponsor Sen. Lindsey Graham  R-S.C.   said  he  remains optimistic about the legislation eventually passing because the missing votes were âactually more about process than substance.â
âWith more hearings  with regular order  weâre going to get 50 votes â  Graham  said during a press conference Tuesday. âWeâre going to fulfill our promise.â
Former Sen. Rick Santorum  who has for some reason or another partnered with  Graham  in this effort  told The Intercept on Tuesday afternoon that  he  is confident Sen. Lisa Murkowski  a key Republican holdout from Alaska  will come around next year if  the bill  goes through the normal committee process. âI know having talked to Lisa just a couple hours ago  she thinks itâs a good idea and she thinks the idea will stand up under public scrutiny  and it makes it an easier vote for everybody â  he  said.
 Graham  and  his  co-conspirators previously said  they  would demand that tax cuts and health care reform be lumped together if  they  failed to make headway on health care in September. But on Tuesday   Graham  changed course  saying  he  is now willing to let tax reform go ahead on its own because  he  had been unaware how complex tying the two together would be. Then  in the spring   Graham  said   he  will insist on a new budget resolution that allows for another crack at repeal using a 50-vote threshold â what is called budget reconciliation in the Senate.
In her statement released after the bill was officially yanked from the floor  Murkowski did indeed express openness to the framework Graham and co-sponsor Sen. Bill Cassidy had constructed. âI recognize the status quo with health care in this country is unacceptable. Giving control back to the states and flexibility are ideas I can get behind â she said. âBut substance matters and the ability to validate data matters.â
This is where it gets macabre. McCain  a key ânoâ vote  is living with a brain cancer diagnosis that is nearly always fatal. The same cancer took the life of his good friend  Sen. Ted Kennedy  and almost upended the push to pass the Affordable Care Act  after Scott Brown filled his seat. Were McCain to lose his battle with cancer  Arizonaâs GOP governor would appoint a Republican rubber stamp. Depending on the circumstances  some Republicans  such as McCainâs best friend Graham  may oppose rushing forward with repeal on pure human decency grounds.

KANSAS CITY  Mo. â  Justin Houston âs once-perfect team had lost consecutive games after a pair of uncharacteristic showings. The Kansas City Chiefs defense couldnât stop anybody  and the offense suddenly lost its effectiveness in the rushing department  which had served as a calling card during the team's 5-0 start.
 Houston   a seventh-year veteran and one of the longest-tenured Chiefs  looked around the locker room  diagnosed the problem and decided he had to speak up.
âIâm from a big family  so I understand there are times to follow  and there are times to lead. There are times to speak up â  Houston  told USA TODAY Sports after Monday night's 29-19 defeat of the Denver Broncos. âWe just werenât having fun.
And  most importantly to  Houston  and his teammates  the Chiefs had fun in the process.

Example Input: The uniformed members of the Bellefontaine Neighbors Police Department were injured in an encounter with a gunman around 7:15 a.m. local time  but expected to survive  according to Sgt.  Shawn McGuire of the St. Louis County Police Department.
  McGuire  said the incident began when the department received a call Wednesday night about shots fired in the suburb. Police were unable to locate the person related to the report  but they remained in the area overnight near a residence where they thought the shots potentially came from.
In the morning  police received a call from a neighbor who saw someone leave the house. Two officers located the individual  a 37-year-old man  walking down the street and tried to have a dialogue with him  according to  McGuire .
The officers ultimately attempted to take the man into custody and a scuffle ensued. At some point  the man took out a firearm and shot the officers   McGuire  said.
Ballistic vests worn by the officers blocked the rounds of gunfire but they still suffered some injuries. Both were hospitalized for treatment and evaluation  according to  McGuire .
The firearm used to shoot the officers has not yet been recovered   McGuire  said. The St. Louis County Police Department was on scene assisting with the barricaded suspect.
