On June 2 HBO, MTV, and a host of celebrities will be joining Michael Bloomberg and other pro-gun control groups to watch participating mayors proclaim “Gun Violence Awareness Day” in their cities.

Those participating will “wear orange” and MTV will “change its on-air logo — as well as several of its social media avatars — to orange in recognition of National Gun Violence Awareness Day.”

According to PRNewsWire, participating celebrities–aka, “cultural influencers”–include:

Julianne Moore, Russell Simmons, Sarah Silverman, Michael Stipe, Patti Smith, Aasif Mandvi,Alyssa Milano, Padma Lakshmi, John Hodgman, Amanda Peet, Perez Hilton, Melissa Joan Hart, Tiffani Thiessen, Tunde Adebimpe of TV On The Radio, Rise Against, Mario Batali, Anti-Flag, Nigel Barker, Grace Weber, Jon Foreman, Judith Hill, Amber Coffman of Dirty Projectors, Tyler Glenn of Neon Trees and Thomas Roberts of MSNBC.

On December 29, 2014, Breitbart News reported that Julianne Moore became the celebrity face for Everytown for Gun Safety’s year-end donations drive. CTNews reported that Moore wrote a letter asking possible contributors to cough up “$5 or more” to “stop gun violence” and “save lives.”

On April 30, 2015, Breitbart News reported that Melissa Joan Hart signed on for Moms Demand Action’s Mother’s Day week gun control push. The push was largely out-shadowed by the number of Americans flocking to gun stores to get guns and bullets for self-defense following the Islamic attack in Garland at the start of Mother’s Day week.

In addition to the celebrities, Motown Records and Essence Magazine will be joining HBO and MTV in support of “Gun Violence Awareness Day.”

Participating Senators include Chuck Schumer (D-NY), Dick Durbin (D-IL), Richard Blumenthal (D-CT), and Al Franken (D-MN).

Senator Chris Murphy (D-CT) is also participating.

In August 2013 Breitbart News reported that Murphy broke with Thomas Jefferson on the source of unalienable rights–which includes guns rights–by saying the right to keep and bear arms is “not a God-given right.” You’ll recall that Jefferson famously explained that we “are endowed by [our] Creator with certain unalienable Rights“

Congressional participants include Representative Mike Thompson (D-CA), who recently won “Top Gun” in a Congressional skeet shoot then used his acceptance comments to call for more gun control. Also included are Reps. Elizabeth Esty (D-CT), Jim Himes (D-CT) and the lone Republican–Bob Dold (R-IL).
