In preparation for the memorial service, he said, thousands of people are expected to attend the event to honour those killed in the tragic incident. "We are overwhelmed by the response," Dhaliwal said.
The memorial service is scheduled from 9 am to 11 am (local time).
On Thursday, Walker had an emotional meeting with the victims' families. "That was obviously private but very emotional," his spokesman said.
Walker also announced that from Friday to August 17, he would place a visitor's book in the state Capitol rotunda where visitors could write notes of condolence to the Sikh community. The book will be kept for one week at the visitors desk in the Capitol and then delivered by the governor's office to the Sikh community in Oak Creek.
"Since the terrible acts of violence committed last Sunday at the Sikh Temple in Oak Creek, our entire state has been focusing on supporting the victims, their families, and the survivors of this tragedy and on helping the entire community and state to heal," he said.
"While we are still trying to determine exactly what motivated the killer, it's important to note discrimination and violence targeted toward a specific ethnic or religious group runs contrary to America's core ideals. By placing it in the First Amendment to the US Constitution, our founding fathers placed special emphasis on protecting religious freedom for all Americans.We must show constant vigilance in defending our founding principles," Walker said in his weekly radio address.Gunman goes on rampage in Wisconsin Gurudwara; 7 dead
