 Paul, during an interview with a Kentucky radio station, said he was concerned that there "is going to be an assassination," after a few tense weeks around the Capitol because of the Supreme Court fight. 
  
 "I really worry that someone is going to be killed and that those who are ratcheting up the conversation ... they have to realize that they bear some responsibility if this elevates to violence," Paul said.

 "These are people that are unstable. We don't want to encourage them,” he added. “We have to somehow ratchet it down and say we're not encouraging them that violence is ever OK.” 
  
 Paul was asked on the radio show about Sen. Cory Booker Cory Anthony BookerWarren lays out foreign policy agenda ahead of 2020 Trump’s court picks held hostage by Mueller bill If the GOP wants to win, it needs to champion the middle class MORE (D-N.J.), who urged members of a group advocating for an end to homelessness to "get up in the face of some congresspeople and tell them about common sense solutions." 
  
 “I think what people need to realize, that when people like [Sen.] Cory Booker say ‘get up in their face,’ he may think that that's OK,” Paul added. “But what he doesn't realize is that for about every thousandth person that might want to get up in your face, one of them is going to be unstable enough to commit violence.” 
  
 Paul's wife, Kelley Paul, wrote an op-ed to Booker in which she appeared to blame him for the threats and protests her husband has faced this past week. Booker's office argued, in a separate op-ed, that his remarks are being taken out of context and that he "has nothing but respect and admiration" for Paul and his family.

The heated debate led to Republican senators, and some Democrats, being confronted by activists in hallways around Capitol Hill, at D.C.-area airports and restaurants and in their cars.

Rand Paul said on Tuesday he worries that the current political climate will lead to deadly violence — including an assassination. 
  
 Paul was referring to tensions over Judge Kavanaugh’s confirmation to the Supreme Court after being accused of sexual misconduct by three women, which have led to thousands of protesters storming the capital. He said the country’s deep divisions might lead to violence and it’s up to politicians to calm things down, not ratchet it up. 
  
 “I fear that there’s going to be an assassination,” Paul said in an interview with Kentucky radio station WHAS. “I really worry that somebody is going to be killed, and that those who are ratcheting up the conversation, they have to realize they bear some responsibility if this elevates to violence.” 
  
 Paul referenced New Jersey Senator Cory Booker- who told his supporters to voice their needs directly to politicians. Paul’s wife Kelley recently wrote an Op-Ed on CNN revealing she and her husband face constant threats. 
  
 “When people like Cory Booker say get up in their face … What he doesn’t realize is that for every 1,000 persons who want to get up in your face, one of them is going to be unstable enough to commit violence,” Paul said. 
  
 Paul cited his 2017 assault by a neighbor that left him with broken ribs and the June 2017 congressional baseball practice where 5 people were shot, including Louisiana Rep. Steve Scalise, the House Majority Whip. 
  
 “When I was at the ball field and Steve Scalise was nearly killed, the guy shooting up the ballfield, and shooting I think five or six people, he was yelling, ‘This is for health care,'” Paul said. “When I was attacked in my yard and had six of my ribs broken, and pneumonia, lung contusion, all that — these are people that are unstable, we don’t want to encourage them.”

 (CNN) An open letter to Senator Cory Booker: 
  
 Kelley Paul and Senator Rand Paul. 
  
 It's nine o'clock at night, and as I watch out the window, a sheriff's car slowly drives past my home. I am grateful that they have offered to do extra patrols, as someone just posted our home address, and Rand's cell number, on the internet -- all part of a broader effort to intimidate and threaten Republican members of Congress and their families. I now keep a loaded gun by my bed. Our security systems have had to be expanded. I have never felt this way in my life. 
  
 In the last 18 months, our family has experienced violence and threats of violence at a horrifying level. I will never forget the morning of the shooting at the congressional baseball practice, the pure relief and gratitude that flooded me when I realized that Rand was okay. 
  
 He was not okay last November, when a violent and unstable man attacked him from behind while he was working in our yard, breaking six ribs and leaving him with lung damage and multiple bouts of pneumonia. Kentucky's secretary of state, Alison Lundergan Grimes, recently joked about it in a speech. MSNBC commentator Kasie Hunt laughingly said on air that Rand's assault was one of her "favorite stories." Cher, Bette Midler , and others have lauded his attacker on Twitter. I hope that these women never have to watch someone they love struggle to move or even breathe for months on end. 
  
 Earlier this week, Rand was besieged in the airport by activists "getting up in his face," as you, Senator Booker, encouraged them to do a few months ago. Preventing someone from moving forward, thrusting your middle finger in their face, screaming vitriol -- is this the way to express concern or enact change? Or does it only incite unstable people to violence, making them feel that assaulting a person is somehow politically justifiable?

Already the target of death threats, including from a person who threatened to chop up his family with an ax, Rand Paul worries the current political climate could spawn deadly violence. "I fear that there's going to be an assassination … I really worry that somebody is going to be killed," the Republican senator from Kentucky told WHAS on Tuesday, referring to Justice Brett Kavanaugh's confirmation and ongoing protests in Washington. "Those who are ratcheting up the conversation, they have to realize they bear some responsibility if this elevates to violence," he added, referencing Sen. Cory Booker's call in June for activists concerned with ending homelessness to "get up in the face of some congresspeople," per the Hill. "What he doesn't realize is that for every 1,000 persons who want to get up in your face, one of them is going to be unstable enough to commit violence," Paul said, per Time. "When I was at the ballfield and Steve Scalise was nearly killed, the guy shooting up the ballfield … was yelling, 'This is for health care.'" His comments echoed a recent CNN op-ed by his wife, Kelley Paul, who also called out Booker. "Preventing someone from moving forward, thrusting your middle finger in their face, screaming vitriol—is this the way to express concern or enact change?" she wrote. Describing "violence and threats of violence at a horrifying level," she added, "I now keep a loaded gun by my bed."
