Actor Kirk Cameron and YouTube personalities Diamond and Silk are coming to this year’s Western Conservative Summit in Denver, the Centennial Institute says.

The conservative think tank at Colorado Christian University in Lakewood released the first names in its lineup for the annual gathering June 8 and June 9 at the Colorado Convention Center.

Cameron starred on the TV show “Growing Pains” from 1985 to 1992 and is a spokesman for his Christian faith in his public life. Diamond and Silk, whose real names are Lynette Hardaway and Rochelle Richardson, are popular personalities on YouTube and on conservative talk shows for their support (and humor) around President Trump.

The initial list also includes Colorado’s U.S. Sen. Cory Gardner of Colorado; Frank Gaffney, president of Center for Security Policy; Charlie Kirk, founder of Turning Point USA; the Reagan administration’s Attorney General Ed Meese; and U.S. Rep. Mark Meadows from North Carolina.

The Centennial Institute said more names would be released in the next few weeks. Each year the event attracts what is believed to be the largest gathering of conservatives outside the nation’s capital, attracting well-known and emerging national candidates.

“We are pleased to have another year of great speakers for the Conservatives in the West,” Jeff Hunt, chairman of the Western Conservative Summit, said in a statement.

“This summit is very important. While most conservative gatherings take place in Washington, D.C., this summit takes place in the heart of the West!”
