After a day-long Twitter spat with the senatorial candidate from Alabama, the late-night host said he was happy to accept an in-person meeting offered by Moore.
"I responded and he responded back and I responded again, it's all on Twitter," Kimmel said on "Live!" Thursday night. "The bottom line is this. I accept the invitation. I will come down there."
A Washington Post article last month detailed allegations against Moore by multiple women who said he acted inappropriately with them, including one woman who said she was assaulted by Moore when he was 32 and she was 14 years old in the 1970s. Moore has categorically denied all allegations against him, and even attacked the women for lying. Moore has blamed "liberals" looking to sabotage his campaign at most of his campaign stops since the news broke.
It seems unlikely Moore expected Kimmel to agree to a visit, but the comedian mocked reports Moore was banned from a mall for harassing women in his acceptance.
"What I'm going to do is -- I think you're going to like this, Roy. I'm going to come to Gadsden, Alabama, with a team of high school cheerleaders, OK? We'll meet you at the mall," Kimmel joked. "Don't worry, I can get you in."
Kimmel, who said he was a Christian, wanted to discuss "Christian values" with the candidate.
"If you're open to it, when we sit down, I will share with you what I learned at my church," Kimmel said in his monologue. "At my church, forcing yourself on underage girls is a no-no."
Kimmel said he was ready for a fight, too, should it come to that.
"Maybe you say come to Alabama and do it man to man, maybe you're challenging me to a fight, which is kind of what it sounds like. If you are, I accept, by the way. I accept that invitation," Kimmel said to cheers from his audience.
Kimmel went on to say they could fight for charity, with the host saying he'd donate the money to the women accusing Moore of misconduct.
Moore spoke at Bryan Baptist Church in Dora, Alabama on Thursday night, delivering what he called a speech on "God and country." Moore attacked his opponent, Doug Jones, for his tolerance of "sodomy" and "transgenders in the military," saying, "I do not hate homosexuals. I do not hate transgenders. I hate sin."
