[Q]: Appearing on CBS’s "Face The Nation" with host John Dickerson on Sunday   Sen. Rand Paul (R-KY)  described  his  painful recovery from the attack by  his  Democratic neighbor as a "living hell." Law enforcement officials arrested and charged  Paul ’s neighbor  Rene Boucher  for the attack in which  he  allegedly ran up and tackled  Paul  from behind.
"It was sort of  I guess  a living hell for the first four or five weeks "  Paul  said. "Couldn't get out of bed without assistance. Six broken ribs  damage to my lungs. Two bouts of pneumonia. It was really a tough go of it  but each day I feel a little bit better. This last month  I've been doing better."
Dickerson then asked  Paul  if he has discussed with his colleagues how politics has become uglier in recent years.  Paul  was one of the Republicans that was attacked last summer during a baseball practice by Democrat activist-turned-terrorist James Hodgkinson  who attempted to murder the group of Republican lawmakers.
"You know  my colleagues come up all the time  and they want to make sure that there is some kind of deterrence  because people don`t want to think that it`s open season on our elected officials "  Paul  continued. "I was also at the baseball field when we were shot at with automatic — semiautomatic fire  and Steve Scalise was severely wounded. And I was 10 feet from a young staffer who was shot in the leg."
"We usually don't ask if someone's raped or mugged — why the person did it "  Paul  noted. "We want punishment and deterrence  and I guess that's what I'm mostly about. I just don't think of any kind of motivation or justification  whether it's political or personal  to attack someone who's unaware from behind in their own yard."

[Q]: Sen. Bob Corker (R-TN)  speaks with reporters after announcing  his  retirement at the conclusion of  his  term on Capitol Hill in Washington  U.S.  September 26  2017. REUTERS/Aaron P. Bernstein
WASHINGTON (Reuters)  - U.S. Senator Bob Corker   the influential Republican chairman of the Senate Foreign Relations Committee  said on Tuesday he will not run for re-election  a blow to a party already struggling to balance divisions between mainstream and more populist wings.
An establishment Republican   Corker  has been criticized from the right  and a conservative activist had already announced a primary challenge. But he was expected to keep the seat  and had amassed a $7.5 million campaign war chest.
 Corker  has ruled out running for governor of Tennessee.
âI have no idea what Iâm going to do. No idea whatsoever â  Corker  said in an interview. But he said he was not leaving out of frustration over deep party divides that have often paralyzed Congress.
 Corker  announced  his  retirement on the day of the failure of the latest Republican effort to repeal former Democratic President Barack Obamaâs healthcare law.
âI am not going to be one of the people who leaves here badmouthing what is one of the greatest privileges of oneâs life â  Corker  said.
He said he realized he was ready to retire on Aug. 24 during a factory groundbreaking in Clarksville  Tennessee  and almost announced his decision at least twice before Tuesday.  Corker  said that he made his announcement now to allow a strong candidate time to enter the Senate race.
 Corker  is the first senator to announce  his  retirement ahead of the 2018 mid-term elections  when one-third of the 100-seat chamber will be up for grabs. Tennessee is a solidly Republican state and the party  which currently holds a 52-seat majority in the Senate  is favored to keep his seat.
In his official announcement   Corker  said that âafter much thought  consideration and family discussionâ over the past year  he and his wife Elizabeth âhave decided that I will leave the United States Senate when my term expires at the end of 2018.â

CLASHES WITH  TRUMP
In August  after Trumpâs much-criticized reaction to violence at a white supremacist rally in Virginia   Corker  told reporters in  his  home state Tennessee that Trump had not been able to demonstrate the âstabilityâ or competence that  he  needed to be successful as president.
After the exchange  the two men had an hour-long meeting at the White House this month that  Corker  has described as a wide-ranging and friendly discussion.
 Corker  will remain chairman of the Foreign Relations Committee until he leaves in January 2019. He said he wanted the panel to address issues including Secretary of State Rex Tillersonâs State Department reorganization  food aid reform  and the fight against human trafficking and modern slavery.
 Corker  said the committee would address the international nuclear agreement with Iran  as Trump faces a mid-October deadline for deciding whether to certify that Tehran is complying with that pact. That decision could force Congress to decide whether to reimpose sanctions.  Corker  would not say whether Trump had decided to certify or not.

[Q]: Prime Minister Boyko Borissov  a former bodyguard to the Soviet-era Communist dictator   welcomed fellow conservatives who run the three main Brussels political institutions to Sofia  pledging to help ease tensions between east and west inside the EU and between the Union and its Russian and Turkish neighbors.
Though the presidency of the EU offers little direct power  it offers Borissov a platform which  he  used to renew Bulgarian demands to be allowed to join Schengen and the euroâs âwaiting roomâ  the ERM-2 exchange rate mechanism. Worries over organized crime and Bulgariaâs relative poverty have stood in its way.

That will not in itself overcome resistance from wary member states.  Borissov âs finance minister said frustration had grown to such an extent that he was ready to call their bluff and apply for the next step toward the euro zone in order to force them to publicly explain their objections.
Warm words from the visitors from Brussels did not drown out opposition at home to the government.  Borissov  dismissed out of hand accusations of shrinking media freedom and  his  minister in charge of the EU presidency denounced a website run by critical journalists covering the issue as âhate speechâ and âfake newsâ.
