Wednesday’s (Nov. 8) mass shooting at the Borderline Bar & Grill in Thousand Oaks, Calif. leaves the country music community in a state of mourning.

Many artists including Cassadee Pope, LeAnn Rimes, John Rich and Morgan Wallen have expressed their sympathies for the victims and their families on social media as artists did following 2017’s Route 91 Harvest Festival.

President Donald Trump supported those affected and the local emergency response teams via Twitter.

He also issued a proclamation on Thursday (Nov. 8) ordering flags be flown at half-staff in remembrance of those who died.

Actress Tamera Mowry-Housley and husband Adam Housley are among those affected by the tragedy. On Thursday afternoon (Nov. 8), they confirmed their niece Alaina died as a result of the shooting. Beforehand, her suitemate said on Twitter a handful of girls in her residence hall had gone to the Borderline, and Alaina was the only one not accounted for.

Aubrie Sellers, one of CMT’s Next Women of Country, also had plans to go to the Borderline on Wednesday.
