He opened fire and landed a bullet on the candidate's clothes. Erika Shields, chief of the Louisville Metro Police said that the suspect was taken into custody by responding officers and no one was injured.
"I am blessed. Our team is blessed. One man entered our office. "We greeted him, and he began shooting at me," Craig Greenberg, the candidate, stated at Monday's press conference.
Shields stated that it appeared Greenberg was the victim. The suspect is believed to have acted alone and police don't know why.
Greenberg stated that five people were in the office at time of shooting. Greenberg immediately tweeted that he and his employees were safe after the shooting.
Greenberg stated that "much more work" was needed to reduce gun violence in Louisville.
Political leaders labelled Monday's news of the attack "scary" and "horrible".
According to CBS Louisville affiliate WLKY, Governor Andy Beshear stated that he spoke to him "as soon as I got the news". "He is physically fine. We are praying for his safety and that of his family. Although I understand what it is like to be threatened, this is an extra step.
David James, President of Louisville Metro Council, stated that an "individual tried to assassinate Louisville mayor candidate Craig Greenberg."
Shields stated Monday, earlier in the day that they were "looking at this from all angles", when Shields was asked if there was concern that other candidates for the mayor might be being targeted. "Until we determine the motivating factors, we will keep an open mind" and continue to be cautious with many members of our community.
